A ball A with a mass of 3 kg is thrown with a velocity of 4 m/s horizontally at a block B with a mass of 25 kg that is suspended from ropes. After the collision, you observe that the block increased in height by an amount h = 3 cm. What was the coefficient of restitution for the collision? HINT: Use h to determine the state of the block immediately after the collision and then use that information to determine e.
