Question

Abet strikes a 0.145-kg baseball. Just before impact, the ball is travelling horizontally to the right at 50.0 m/.s. and it leaves the bat traveling to the left at an angle of 40 degree above horizontal with a speed of 55.0 m/s the ball and bat are in contact for 1.85 ms. 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. Express your answer using two significant figures.

Explanation / Answer

part a)

for the horizontal component of average force

horizontal component of average force = change in horizontal momentum/time

horizontal component of average force = 0.145 * (- 55 * cos(40) - 50)/.00185

horizontal component of average force = -7221.2 N

part b)

for the vertical component of average force

vertical component of average force = change in vertical momentum/time

vertical component of average force = 0.145 * (55 * sin(40))/.00185

vertical component of average force = 2771 N
