A block of mass 3.60 kg is placed against a horizontal spring of constant k = 865 N/m and pushed so the spring compresses by 0.0450 m.
a) What is the elastic potential energy of the block-spring system (in J)?
b) If the block is now released and the surface is frictionless, calculate the block's speed (in m/s) after leaving the spring.
A tennis ball initially moves with a velocity of 28.0 m/s horizontally to the right. A tennisracket strikes the ball, giving it a velocity of 28.0 m/s to the left. Treat the collision aselastic and the ball and racket as particles ofmass 0.0580 kg..
