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 1.75ms .

Part A

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

Express your answer using two significant figures.

Part B

Find the vertical component of the average force on the ball.

Express your answer using two significant figures.

Explanation / Answer

A) Apply impulse = chnage in momentum

Fx*dt = m*(v2x - v1x)

Fx = m*(v2x - v1x)/dt

= 0.145*(-65*cos(35) - 60)/(1.75*10^-3)

= -9383 N <<<<<<<-------------Answer

B) Apply impulse = chnage in momentum

Fy*dt = m*(v2y - v1y)

Fy = m*(v2y - v1y)/dt

= 0.145*(65*sin(35) - 0)/(1.75*10^-3)

= 3089 N <<<<<<<-------------Answer
