A bat exerts force of 755N on a 320g ball that approaches the bat at 40 m/s and leaves at 64 m/s. How long was the ball in contact with the bat?
change of momentum = force * time
.320 (40+64) = 755 t
thank you!
You are welcome.
why do you add the 40 and 64...should you not calculate the change in them?
opposite directions
64 - (-40) = 64 + 40
