A 0.30 kg ball is tied to a 38 cm long string and released from a horizontal position. It swings down, colliding with a wad of putty of mass 0.50 kg. After the collision, the block and putty stick together and swing up. The ball and putty have sizes negligible to the length of the string.
(a) What is the velocity of the ball just before the collision?
(b) Determine the velocity of the ball and putty just after the collision.
(c) Find the maximum height of the ball and putty after the collision.
