Question

As a baseball is being caught, its velocity goes from 32.0 m/s to 0.0 m/s in 0.0050 s. The mass of the baseball is 0.125 kg.

(a) What is the baseball's acceleration?
m/s2

(b) What are the magnitude and direction of the force acting on it?
N

a.)same direction as velocity of the ball
b.)opposite in direction to velocity of the ball


(c) What are the magnitude and direction of the force acting on the player who caught it?
N

a.)same direction as velocity of the ball
b.)opposite in direction to the velocity of the ball

Explanation / Answer

(a). acceleration a = change in velocity / time
                      = (0-32)/0.005 = -6400m/s2.
(b).
       b.)opposite in direction to velocity of the ball
(c). magnitude of force acting on the player = ma = 800N
         a.)same direction as velocity of the ball
