The girl throws 0.8 kg ball toward the wall with an initial velocity VA = 15 m/s as shown in Fig. 2. Parameters are given in Fig. 2. Ball is considered as a particle and there is not friction between the ball and the wall. Determine the velocity of the ball at which it strikes the wall at B. (10 marks) Calculate the velocity of the ball at which it rebounds from the wall if the coefficient of restitution e = 0.6. (15 marks) Determine the distance s (see Fig. 2) from the wall to where it strikes the ground at C. (15 marks)

A mball = 0.5 kg cannonball and is shot with an initial velocity of vA at an angle θ1. The cannonball bounces off the ground at point B. The coefficient of restitution between the ball and ground is e = 0.15. Ignore air resistance. Hint: Assume the ground is so large that it will not move. Values for the figure are given in the following table. Note the figure may not be to scale. Variable Value vA60 msd13 mθ124 degrees For all velocities, include negatives for direction if appropriate. a. Determine the y-component of the velocity of the cannonball right before it hits the ground, (VBy)1 b. Determine the y-component of the velocity of the cannonball right after it hits the ground, (VBy)2. c. Determine the max height the cannonball reaches after it hits the ground, h. Round your final answers to 3 significant digits/figures. (VBy)1 = m s (VBy)2 = m s h = m

A hanging weight, with a mass of m1 = 0.360 kg, is attached by a string to a block with mass m2 = 0.850 kg as shown in the figure below. The string goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is μk = 0.250. At the instant shown, the block is moving with a velocity of vi = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the string does not stretch and does not slip on the pulley, and that the mass of the string is negligible. (a) Using energy methods, find the speed of the block (in m/s ) after it has moved a distance of 0.700 m away from the initial position shown. m/s (b) What is the angular speed of the pulley (in rad/s) after the block has moved this distance? rad/s
