Question

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 60.0m/s , and it leaves the bat traveling to the left at an angle of 35? above horizontal with a speed of 65.0m/s . The ball and bat are in contact for 1.85ms .

Part A

Find the horizontal component of the average force on the ball. Take the x-direction to be positive to the right

Fy = N Fx = N

Explanation / Answer

V1x = +60

v1y = 0

V2x = -V2*cos35 = -65*cos35 = -53.24

V2y = +v2*sin35 = +37.28 m/s

t = 1.85e-3 s

Fx = m*(V2x - V1x) /t

Fx = (0.145*(-53.24-60))/1.85e-3 = -8.87*10^3 N <-answer

+++++++

part B

Fy = m*ay = (m*(v2y - V1y))/t

Fy = (0.145*37.28)/1.85e-3

Fy = 2.92*10^3 N <----answer
