Question

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at a speed of 45.0m/s, and it leaves the bat traveling to the left at an angle of 40degree above horizontal with a speed of 65.0m/s . The ball and bat are in contact for 1.85ms. 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. Find the vertical component of the average force on the ball. The positive y-axis points upwards. Express your answer using two significant figures.

Explanation / Answer

F(x) = [mV(x)f - mV(x)i]/t = (.145)[-65Cos(40) - 45]/(.00185) = - 7429.7 N F(y) = [mV(y)f - mV(y)i]/t = (.145)[65Sin(40) - 0]/(.00185) = 3274.74 N
