Question

A 150g tennis ball comming at a speed of 40m/s is hit straight back by a bat to speed of 60m/s.the magnitude of the average force F on the ball when it is in contact for 5ms with the bat is. Don't spam.i need step wise clear explanation

Answer 1

Answer:

-3×10^3N

Explanation:

force=change in momentum/time

initial momentum=0.15×40=6kgm/s

final momentum =0.15×-60=(-9kgm/s)

force=(-9-6)/5×10^-3N

=-15/5 ×10^3N

=(-3)×10^3N

Answer 2

Force = Change in momentum/Time

= Final momentum - Initial momentum/Time

= -9 - 6/5×10-³

= -15/5×10-³

= -3×10³ N

Hope it helps!!

Thank you ✌️
