Question

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 45.0m/s , and it leaves the bat traveling to the left at an angle of 30? above horizontal with a speed of 60.0m/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

Express your answer using two significant figures.

I need part B

Part B

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

Express your answer using two significant figures.

-7600

Explanation / Answer

Favg-y *t= m*u2*sin 30 = 0.145*60*0.5 = 4.35...

FAavg-y = 4.35/t = 4.35/(1.85*10^-3) = 2351.35 N
