Estimate what must the baseballs speed be

Reference no: EM13557647

A pitcher claims he can throw a 0.145-kg baseball with as muchmomentum as a 3.00-g bullet moving with a speed of 1.50 x 103m/s.

a) What must the baseball's speed be if the pitcher's claim is valid?

b) Which has greater kinetic energy, the ball or thebullet?
