1 Part Two: Earlier Material Problem 1: (Momentum and Impulse) A superball of m 1 = 0.08kg, starting at rest, is dropped from a height falls h 0 = 3.0m above the ground and bounces back up to a height of h f = 2.0m. The collision with the ground occurs over =5.0ms. t c a) What is the momentum of the ball immediately before the b) What is the momentum of the ball immediately after the c) What is the average force of the table on the ball? d) What impulse is imparted to the ball? e) What is the change in the kinetic energy during the 1 1 f) Assume that the rubber has a specific heat capacity of c = 0.48cal g 0 r C and that all the lost mechanical energy goes into heating up the rubber. What is the change in temperature of the superball? Problem 2: (Conservation of Energy and Momentum) An object of mass m 1 =1.5kg is initially moving with a velocity v 0. It collides completely inelastically with a block of mass m 2 = 2.0kg. The second block is attached 3 1 to a spring with constant k = N m. The block and spring lie on a frictionless horizontal surface. The spring compresses a distance d = m. a) What is the velocity of the object of mass m 1 and the block immediately after the
2 b) What is the initial velocity of the object of mass m 1 immediately before the c) If the block were attached to a very long string and hung as a pendulum, how high would the block and object of mass m 1 rise after the Let g = 9.8m s 2. Problem 3: (Angular Dynamics) 2 F = N at the rim of the merry- A playground merry-go-round has a radius of R = 4.0m and has a moment of go-round for a time t = s. 2 inertia I = cm kg m about an axis passing through the center of mass. There is negligible friction about its vertical axis. Two children each of mass m = 25kg were standing on opposite sides a distance r 0 = 3.0m from the central axis. The merry-go-round is initially at rest. A person on the ground applied a constant tangential force of a) What was the angular acceleration of the merry-go-round? b) What was the angular velocity of the merry-go-round when the person stopped applying the force? c) What average power did the person put out while pushing the merry-go-round? d) What was the rotational kinetic energy of the merry-go-round when the person stopped applying the force? The two children then walked inward and stop a distance of r 1 =1.0m from the central axis of the merry-go-round. e) What was the angular velocity of the merry-go-round when the children reached their final position? f) What was the change in rotational kinetic energy of the merry-go-round when the children reached their final position?
