Question

A 0.25 kg baseball is in contact with a bat for 0.0075 s and exerts a force of 18,500 N. What impulse is delivered to the ball?

Answer 1

Impulse is Force × time = 18500 × 0.0075

138.75 Ns

Answer 2

Answer : The impulse delivered to the ball is 138.75 N.s

Explanation :

Impulse : It is defined as the force applied to an object for a certain amount of time.

Formula used :

$I=F\times t$

where,

I = impulse

F = force = 18500 N

t = time = 0.0075 s

Now put all the given values in the above formula, we get:

$I=(18500N)\times (0.0075s)$

$I=138.75N.s$

Therefore, the impulse delivered to the ball is 138.75 N.s
