- Two blocks, with masses mA and mB, are connected to each other and to a central post by thin rods as shown in Fig. 5-41. The blocks revolve about the post at the same frequency f (revolutions per second) on a frictionless horizontal surface at distances rA and rB from the post. Derive an algebraic expression for the tension in each rod.Two boxes are connected by a rope that passes over a pulley (Figure 6-31). Box #1 is on a ramp inclined at 35° to the horizontal, and the coefficient of kinetic friction between the box and ramp is 0.54. The masses of the boxes are m1 5 2.5 kg and m2 5 5.5 kg. Neglecting the motion of the pulley and assuming that the velocity of each box is in the same direction as its acceleration, what is the magnitude of the acceleration of the boxes?An amusement park ride consists of a large vertical cylinder that spins about its axis fast enough that any person inside is held up against the wall when the floor drops away (Fig. P5.60). The coefficient of static friction between person and wall is s, and the radius of the cylinder is R. (a) Show that the maximum period of revolution necessary to keep the person from falling is T=(42Rs/g)1/2. (b) If the rate of revolution of the cylinder is made to be somewhat larger, what happens to the magnitude of each one of the forces acting on the person? What happens in the motion of the person? (c) If the rate of revolution of the cylinder is instead made to be somewhat smaller, what happens to the magnitude of each one of the forces acting on the person? What happens in the motion of the person?
- In Fig. 6-45, a 1.34 kg ball is connected by means of two massless strings, each of length L = 1.70 m, to a vertical, rotating rod. The strings are tied to the rod with separation d = 1.70 m and are taut. The tension in the upper string is 35 N. What are the (a) tension in the lower string, (b) magnitude of the net force on the ball, and (c) speed of the ball? (d) What is the direction of ?At the scene of an accident, two traffic experts appear to determine which of the drivers was at fault considering that it was a highway where the speed limit is 80 km / h. The data collected in the field indicate that the vehicles stuck and skidded together a length of 25 m on the pavement whose dynamic friction coefficient is μk = 0.30. Considering that the masses of vehicles A and B are 2300 kg and 1500 kg, respectively, specify which of the cars was speeding at the moment of impact and by how much it exceeded the speed limit. Express your result in km / h for the purposes of the expertise.A proposed space station consist set of a circular tube that will rotate about its center (like a tubular bicycle tire), Fig. 5-39.

Block 2 is pushed by force F of magnitude 20 N and angle u ? 35°. The coefficient of kinetic friction between each block and the horizontal surface is 0.20. What is the tension in the string? (please don't copy-paste solution)The 3500-lb automobile shown in the picture is traveling down the 10-degree inclined road at a speed of 20 ft/s. If the driver wishes to stop the car, determine how far s the tires skid on the road if the brakes are jammed, causing the wheels to lock. Coefficient of kinetic friction between wheels and road is 0.5.
