As a baseball is being caught, its speed goes from 28.0 m/s to 0.0 m/s in about 0.0050 s. The mass of the baseball is 0.160 kg.
(a) (a) What is the baseball's acceleration?
(b) What are the magnitude and direction of the force acting on it?
(c) What are the magnitude and direction of the force acting on the player who caught it?

-
(a) the AVERAGE acceleration is
a = (28 - 0)/0.005
= 5600 m/s^2
(b) F = ma = 0.160*5600 = 896 N in the direction opposing the balls motion.
(c) same as b but in the opposite direction (towards the player)
a = (28 - 0)/0.005
= 5600 m/s^2
(b) F = ma = 0.160*5600 = 896 N in the direction opposing the balls motion.
(c) same as b but in the opposite direction (towards the player)
