A pitcher claims he can throw a 0.157 kg baseball with as much momentum as a 1.5 g bullet moving with a speed of 1.50 multiplied by 103 m/s.

(a) What must the baseball's speed be if the pitcher's claim is valid?
m/s
(b) Which has greater kinetic energy, the ball or the bullet?

The bullet has greater kinetic energy. The ball has greater kinetic energy.
Both have the same kinetic energy.
