Question

As a baseball is being caught, its velocity goes from 30.5 m/s to 0.0 m/s in 0.0050 s. The mass of the baseball is 0.140 kg.
(a) What is the baseball's acceleration?
1 m/s2

(b) What are the magnitude and direction of the force acting on it?
2. 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?
4. N
A.same direction as velocity of the ball
B. opposite in direction to the velocity of the ball

Explanation / Answer

a .

v = u + at ;

0 = 30.5 + a * 0.005

a = 6100 m /s^2 <--------ans

b .

F = ma

F = 0.140 * 6100 = 854N

B.opposite in direction to velocity of the ball

C .

magnitude= 854 N :

direction

A.same direction as velocity of the ball
