Hello, is it possible to help me solve this question? -A 475-gram ball is traveling horizontally at 12.0 m/s to the left when it is suddenly struck horizontally by a bat, causing it to reverse direction and initially travel at 8.50 m/s to the right. If the bat produced an average force of 1275 N on the ball, for how long (in milliseconds) was it in contact with the ball

Respuesta :

Change in momentum = ΔP

ΔP = F t

Where:

F= force

t = time

Pf - Pi = Ft

M vf - m vi = F t

m= mass = 475 g = 0.475 kg

t = M vf - M vi / F

t = M (vf-vi) / f

Replacing:

t = 0.475 ( 8.50 - (-12 ) )/ 1275 = 0.0076 s = 7.64 ms
