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? 33 kg • 140 kg • 4600 kg • 74,000 kg •

Answer 1

sorry wrong options. answer is 138.75 kg.ms^-1

Answer 2

Correct Answer  138.75N-S : Option is not given .

Explanation :

Given :

mass of base ball= 0.25kg

time=t=0.0075sec

Force=F=18,500N

Impulse =J=?

Formula =Impulse = Force x time

=18,500x0.0075

=138.75 N-S
