Review. As shown in Figure P8.26, a light string that does not stretch changes from horizontal to vertical as it passes over the edge of a table. The string connects m1, a 3.50-kg block originally at rest on the horizontal table at a height h = 1.20 m above the floor, to m2, a hanging 1.90-kg block originally a distance d = 0.900 m above the floor. Neither the surface of the table nor its edge exerts a

A 1.1 g pebble is stuck in a tread of a 0.74 m diameter automobile tire, held in place by static friction that can be at most 3.5 N . The car starts from rest and gradually accelerates on a straight road. How fast is the car moving when the pebble flies out of the tire tread?
As shown, a light string that does not stretch changes from horizontal to vertical as it passes over the edge of a table. The string connects m1, a 3.50-kg block originally at rest on the horizontal table at a height h = 1.20 m above the floor, to m2, a hanging 1.90-kg block originally a distance d = 0.900 m above the floor. Neither the surface of the table nor its edge exerts a force of kinetic friction. The blocks start to move from rest. The sliding block m1 is projected horizontally after reaching the edge of the table. The hanging block m2 stops without bouncing when it strikes the floor. Consider the two blocks plus the Earth as the system. (a) Find the speed at which m1 leaves the edge of the table. (b) Find the impact speed of m1 on the floor. (c) What is the shortest length of the string so that it does not go taut while m1 is in flight?

- We are now going to consider the transport of the grains of pollen in the air. A grain of pollen torn from the stamen by a gust of wind finds itself airborne. It is now in free fall because it only experiences the force due to its weight and a friction force proportional to its speed. Question : Explain why the grain of pollen will reach a limiting speed in its free fall.arrow_forwardA chandelier of mass 18kg hangs from a cable that is attached to a ceiling. The chandelier is at rest and initially the cable hangs vertically.Alice climbs up the stairs to a height level that is close to the chandelier's height. She then pulls the chandelier to one side using a hook, to bring the chandelier closer to her so she can replace a light bulb. The force that Alice exerts on the chandelier is in the horizontal direction and has magnitude 42 N.arrow_forwardA horizontal meter stick has a mass of 235 g.235 g.

- You have been hired as an expert witness in the case of a factory owner suing a demolition company. The particular case involves a smokestack at a factory being demolished. In order to save money, the factory owner wanted to move the smokestack to a nearby factory that was being built. The demolition company guaranteed to deliver the undamaged smokestack to the new factory by toppling the smokestack freely onto a huge cushioned platform lying on the ground. The then-horizontal smokestack would have been loaded onto a long truck rig for transport to the new factory. However, as the smokestack toppled, it broke apart at a point along its length. The factory owner is blaming the demolition company for the destruction of his smokestack. The demolition company is claiming that there was a defect in the smokestack and that is the reason for its destruction. What advice do you give the attorney who is handling the case on the side of the factory owner?arrow_forwardA small block sits at one end of a flat board that is 4.00 m long. The coefficients of friction between the block and the board are μs= 0.450 and μ = 0.400. The end of the board where the block sits is slowly raised until the angle the board makes with the horizontal is α0, and then the block starts to slide down the board. If the angle is kept equal to α0 as the block slides, what is the speed of the block when it reaches the bottom of the board? Express your answer with the appropriate units.arrow_forward47. An inclined plane of angle 20.0° has a spring of 500 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in Figure P7.47. A 2.50 kg is placed on the plane at a m force constant k = ww. block of mass m = Figure P7.47 Problems 47 and 48 distance d 0.300 m from the spring. From this position, the block is projected down- ward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block moment- arily comes to rest?arrow_forward
- Problem 3. James Bond is pursued by evil henchmen across a ski resort. He ends up at the top of a high jump runway, whose slope is 36deg. With nowhere else to go and without his trusty Walther PPK, he has no option but to go for it. He pushes himself off to an initial speed of V0=2 m/s and slides down the runway. The kinetic friction coefficient between his waxed wood skis and the snow is 0.10. The level of the takeoff point of this runway is H=50m below the level of the launch point. At the takeoff point, the runway is horizontal. Below that point, the runway reverts to a 36deg slope. Ignore air resistance. a) What is Bond’s speed with respect to the ground at the takeoff point in m/s and mph? How realistic is this estimate and why? b) What is the location of the landing point with respect to the takeoff point? How realistic is this estimate and why? c) WhatisBond’sspeedatlandinginm/sandmph?Howrealisticisthisestimateandwhy? d)…arrow_forward45. Review.

- A 1.0 kg pendulum block at the end of a 1.0 m long rope(assume rope has no mass). When the 1.0 kg mass hangs vertically undisturbed it is in contact with a second block that sits on a flat horizontal surface. The coefficient of friction between the second block and the horizontal surface is 0.15 for kinetic friction and 0.40 for static friction. The 1.0 kg mass is pulled back to an angle of 60. degrees with respect to the vertical and let go. At the lowest point in its swing, it hits the block. After the collision (which takes 0.070 seconds) the 1.0 kg block bounces off the second block and swings back up to an angle of 12 degrees. What is the maximum mass that the second block can have if it moves after the collision?arrow_forwardYou are a bully. You pin a 48 kg dweeb to a wall so that his feet aren't touching the ground. Your arm is extended so that it makes an angle 28 degrees with the horizontal. The dweeb's back is so sweaty with fear that there is no friction between his back and the wall. What is the magnitude of the force , in N, you must apply to keep the dweeb in equilibrium? (Use g = 10 m/s2) This scenario is represented schematically below. Unfortunately for you, years later the dweeb is your boss and he makes your life miserable. (Please answer to the fourth decimal place - i.e 12.3445)arrow_forwardA 61.9-kg circus performer is fired from a cannon that is elevated at an angle of 57.3 ° above the horizontal. The cannon uses strong elastic bands to propel the performer, much in the same way that a slingshot fires a stone. Setting up for this stunt involves stretching the bands by 2.35 m from their unstrained length. At the point where the performer flies free of the bands, his height above the floor is the same as that of the net into which he is shot. He takes 3.02 s to travel the horizontal distance of 28.7 m between this point and the net. Ignore friction and air resistance and determine the effective spring constant of the firing mechanism.
