baseball pitcher throws a fast ball with a 100 ns impulse. if he applied the force in 0.15 seconds, what force did he apply?

The force applied on the ball is 666.7 N  

Explanation:

Impulse is defined the change in momentum of an object when force is acted on the object for the given interval of time.

Mathematically,

where,

= change in momentum or impulse = 100 Ns

F = force applied on the ball = ?

= time taken = 0.15 s

Putting values in above equation, we get:

Hence, the force applied on the ball is 666.7 N
