Question

A soccer player applies an average force of 180 N during a kick. The kick accelerates a 0.45 kg soccer ball from rest to a speed of 18 m/s. What is the impulse imparted to 
the ball? What is the collision time?

Bot · Answer

Impulse = Force x Time Impulse = 180 N x Time Time = (18 m/s) / (180 N) Time = 0.1 s Impulse = 180 N x 0.1 s Impulse = 18 Ns
