Chapter 9, Problem 21PCE

Predict/Calculate A 0.14-kg baseball moves toward home plate with a velocity $\stackrel{\to }{{\text{v}}_{\text{i}}}=(-36\text{ m/s})\hat{\text{x}}$. After striking the bat, the ball moves vertically upward with a velocity $\stackrel{\to }{{\text{v}}_{\text{i}}}=(18\text{ m/s})\hat{\text{y}}$. (a) Find the direction and magnitude of the impulse delivered to the ball by the bat Assume that the ball and bat are in contact for 1.5 ms. (b) How would your answer to part (a) change if the mass of the ball were doubled? (c) How would your answer to part (a) change if the mass of the bat were doubled instead?
