A tennis ball of mass 57.0 g is held just above a basketball of mass 577 g. With their centers vertically aligned, both balls are released from rest at the same time, to fall through a distance of 1.10 m, as shown in the figure below. (a) Find the magnitude of the downward velocity with which the basketball reaches the ground. m/s (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball while the tennis ball is still moving down. Next, the two balls meet in an elastic collision. To what height does the tennis ball rebound? m

The 0.31-kg mass slides on a frictionless wire that lies in the vertical plane. The spring attached to the mass has a free length of 80 mm and stiffness of 0.13 N/mm. Calculate the smallest value of the distance b so that the mass will reach the end of the wire at B after being released from rest at A.
The cylindrical plug A of mass ma = 3.3 kg is released from rest at B and slides down the smooth circular guide. The plug strikes the block C of mass mc = 3.7 kg and becomes embedded in it. Calculate the distances which the block and plug slide before coming to rest. The coefficient of kinetic friction between the block and the horizontal surface is u = 0.42 and the distance r = 1.42 m.
Find the minimum force P for impending motion of the refrigerator shown, and determine whether it will slip or tip, given:W = 180 lbs, L1 = 4.5 ft, L2 = 3.7 ft, L3 = 2.3 ft, L4 = 1.5 ft, μS = 0.5
Block A has a mass mA and is attached to a spring having a stiffness k and unstretched length l0. If another block B, having a mass mB, is pressed against A so that the spring deforms a distance d, show that for separation to occur it is necessary that d > 2µkg(mA + mB )/k, where µkis the coefficient of kinetic friction between the blocks and the ground. Also, what is the distance the blocks slide on the surface before they separate?
A hammer head H having a weight of 0.26 lb is moving downwards at 40 ft/s when it strikes the head of a nail of negligible mass and drives it into a block of wood as shown. Find the impulse on the nail if it is assumed that the grip at A is loose, the handle has a negligible mass, and the hammer stays in contact with the nail while it comes to rest.

Show complete solutionA body is thrown vertically upward with an initial velocity of 9m/s. Assuming that it falls freely after it comes to rest at the top of its path, find its velocity 2.5s after discharge.
Starting from rest, it takes 1 second for m1 to fall 1.5m. A ring of unknown mass sits on top of m1 as it falls. If m1=2kg and m2=2.5kg, and the incline is frictionless, what force does m1 put on the ring?
The homogeneous sphere with mass m is held 1 m above the horizontal plane and rotates with an angular velocity of 30 rad/s clockwise. The sphere is then released and falls impacting the ground below at A. Determine the velocity of the centre of mass of the sphere after it bounces. Assume the ground is rough so no slipping occurs, and the coefficient of restitution is 0.9. Solve all questions using Impulse and Momentum methods
The collar of mass m is released from rest while in position A and subsequently travels with negligible friction along the vertical-plane circular guide. Determine the magnitude of the normal force exerted by the guide on the collar (a) just before the collar passes point B, (b) just after the collar passes point B (i.e., the collar is now on the curved portion of the guide), (c) as the collar passes point C, and (d) just before the collar passes point D. Use the values m = 0.5 kg, R = 1.0 m, and k = 290 N/m. The unstretched length of the spring is 0.70R.
