Question

A pitcher tosses a baseball in the positive direction with a speed of 12 m/s. If the ball stops after 4 seconds, what is the average acceleration of the ball?
A.) -3 m/s/s
B.) +48 m/s/s
C.) +3 m/s/s
D.) -48 m/s/s

Answer 1

Answer:

option c is correct

Explanation:

we know that time rate of change of velocity is called acceleration

so a=v/t

a=12/4

a=3m/s²
