A spring with spring constant 24 N/m is compressed a distance 8.0 cm by a ball with a mass of 217.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 8.0 cm and is also released, leaving the spring at point A. Assume the ball rolls, but ignore other effects of friction. (Assume that the ball is a solid ball.) (a) What is the speed of the ball at point B? m/s (b) What is the speed of the block at point B? m/s

Q.6. A small point-like piece of clay with mass m = 200 g is traveling at a constant velocity v→0 = (30 m/s) î towards a stationary cylindrical hoop of mass M = 2000 g and radius R = 50 cm that is free to rotate about its central axis which is at the center of the zy-plane. Before sticking to the hoop, the clay is traveling along a horizontal line a distance d = 23 R. The clay impacts and sticks to the hoop at point A. a. What is the angular momentum of the system L → 0 before the collision about the origin? (include unit vector direction) b. What is the moment of inertia of the system after the clay sticks to the rod? c. Find the angular speed ω just after the collision. d. What is the kinetic energy of the system just after the collision? e. At what vertical height y does point A momentarily stop?

Consider a ball of radius r and mass m struck horizontally by the cue stick at height h = 7 cm with a force P, as depicted in the figure below. The ball starts at rest, and the force from the cue stick is much larger than the friction force. The moment of inertia of the ball is IG = 25 mr2, the ball rolls without slipping after the impact, and the linear velocity of the point B on top of the ball is v = 15 cm/s after the impact. a. Calculate the ball's radius r. b. Determine the angular velocity of the ball ω immediately after the impact. c. What is the kinetic energy of the ball immediately after the impact?
