A pitcher claims he can throw a 0.141-kg baseball with as much momentum as a 2.3

Question

A pitcher claims he can throw a 0.141-kg baseball with as much momentum as a 2.32-g bullet moving with a speed of 1.50 times 10^3 m/s. (a) what must the baseball's speed be if the pitchers claim is valid? Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation, carry out all intermediate results to minimize roundoff error. m/s (b) which has greater kinetic energy, the bal or the bullet? The bullet has greater kinetic energy. The ball has greater kinetic energy. Both have the same kinetic energy. A ball of mass m is thrown straight up into the air with an initial speed v_0, (a) Find an expression for the maximum height reached by the ball in terms of v_0 and g.

Explanation / Answer

For the claim to be true.

v(ball) = m(bulet).v(bullet)/m(ball) = (2.32g x 15000m/s)/141g = 24.68m/s

The bullet has a higher kinetic energy as the velocity of the bulet is way higher than the velocity of the ball.
