Review. A student, along with her backpack on the floor next to her, is in an elevator that is accelerating upward with acceleration a. The student gives her backpack a quick kick at t = 0, imparting to it speed v and causing it to slide across the elevator floor. At time t, the backpack hits the opposite wall a distance L away from the student. Find the coefficient of kinetic friction k between the backpack and the elevator floor.
A man exerts a force of 16.7 N horizontally on a box so that it is at rest in contact with a wall as in Figure 6.3. The box weighs 6.52 N. a. Find the static friction force exerted on the box, given the forces being applied, b. If the coefficient of static friction between the wall and the box is 0.50, find the maximum static friction force that may be exerted on the box. Comment on your results.
A sled and rider have a total mass of 56.8 kg. They are on a snowy hill accelerating at 0.7g. The coefficient of kinetic friction between the sled and the snow is 0.18. What is the angle of the hills slope measured upward from the horizontal? You may find a spreadsheet program helpful in answering this question.
An athlete grips a light rope that passes over a low-friction pulley attached to tire ceiling of a gym. A sack of sand precisely equal in weight to the athlete is tied to the other end of the rope. Both the sand and the athlete are initially at rest. The athlete climbs the rope, sometimes speeding up and slowing down as he does so. What happens to the sack of sand? Explain.
Review. A window washer pulls a rubber squeegee down a very tall vertical window. The squeegee has mass 160 g and is mounted on the end of a light rod. The coefficient of kinetic friction between the squeegee and the dry glass is 0.900. The window washer presses it against the window with a force having a horizontal component of 4.00 N. (a) If she pulls the squeegee down the window at constant velocity, what vertical force component must she exert? (b) The window washer increases the downward force component by 25.0%, while all other forces remain the same. Find the squeegees acceleration in this situation. (c) The squeegee is moved into a wet portion of the window, where its motion is resisted by a fluid drag force R proportional to its velocity according to R = 20.0v, where R is in newtons and v is in meters per second. Find the terminal velocity that the squeegee approaches, assuming the window washer exerts the same force described in part (b).
One great form of athletic competition for bulldogs, American pit bull terriers, huskies, and many other breeds is the weight pull. Many of these dogs can pull weights two orders of magnitude greater than their own weight! Railsplitter, an American pit bull terrier, can pull a sled that has a total weight of 2215 lb along a horizontal surface. Suppose he pulls with a horizontal force of 3.50 103 N while friction is also working against the sled. If the magnitude of the net acceleration of the sled is 0.152 m/s2, find the value of the coefficient of kinetic friction, k, between the sled and the pulling surface. (The sled is normally on a set of rails.)
Twenty people participate in a tug-of-war. The two teams of ten people are so evenly matched that neither team wins. After the game they notice that a car is stuck in the mud. They attach the tug-of-war rope to the bumper of the car, and all the people pull on the rope. The heavy car has just moved a couple of decimeters when the rope breaks. Why did the rope break in this situation when it did not break when the same twenty people pulled on it in a tug-of-war?
Review. Figure P5.15 shows a worker poling a boata very efficient mode of transportation across a shallow lake. He pushes parallel to the length of the light pole, exerting a force of magnitude 240 N on the bottom of the lake. Assume the pole lies in the vertical plane containing the keel of the boat. At one moment, the pole makes an angle of 35.0 with the vertical and the water exerts a horizontal drag force of 47.5 N on the boat, opposite to its forward velocity of magnitude 0.857 m/s. The mass of the boat including its cargo and the worker is 370 kg. (a) The water exerts a buoyant force vertically upward on the boat. Find the magnitude of this force. (b) Model the forces as constant over a short interval of time to find live velocity of live boat 0.450 s after the moment described. Figure P5.15

A 100 kg person pushes a box up a ramp at constant speed. The mass of the box is 30 kg, the coefficient of kinetic friction between the box and the ramp is 0.2, and the ramp is inclined 25 degrees above the horizontal. The person (new at pushing boxes up ramps) pushes purely in the horizontal direction. HINT: you must draw complete FBDs to receive full credit. a) Find an expression for the magnitude of the normal force on the box due to the ramp. This answer should be left in variables, not numbers. b) Find the magnitude of the force on the box due to the person. c) Each step the person takes requires a force of static friction so that she does not slip. Find the magnitude of the force of static friction on the person due to the ramp. d) Find the minimum coefficient of static friction between the person's shoes and the ramp, so that this feat is possible
q12 A runner, Ricky ASHER, is travelling at 8.47 m/s. Turning into the final straight, they accelerate at a constant 1.0 m/s2. Their mass is 71 kg. Neglecting air resistance, what vertical force (in kN) does the track exert on them? In this question, it was necessary to perform the following steps. Select all that apply. Hint: Incorrect responses will be penalised. Question 12 options: Convert units by multiplying by 3600. Convert units by multiplying by 1000. Convert units by dividing by 1000. There is no need to convert units because the mass is in kg. Convert units by dividing by 3600.
Instructions Use g = 10 m/s2 Always answer in standard units (SI units). Unless otherwise instructed. Answer to 2 decimal places. Unless otherwise instructed. A) One way to determine the coefficients of friction (μs and μk) between two surfaces is to use an incline plane. Consider a block of mass m = 2.0kg initially at rest at the top of the ramp. The angle θ is increased slowly. The object starts to slide down the ramp when the angle is 40 degree. Determine the value of μs. B) From the above problem, the block slides down the slope with an incline angle of 40 degree, the angle is kept constant. The block starts from rest and travels along the ramp by distance d = 2.0 m in time t = 1.5 s. Determine the value of μk
