Question

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 50.0m/s , and it leaves the bat traveling to the left at an angle of 35 degrees above horizontal with a speed of 60.0m/s . The ball and bat are in contact for 1.65ms .

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

mb = mass of ball = 0.145
mB = mass of bat = ?

v1x = +50 m/s
v2x = -60 sin35
v2y = -60 sin35
?t = 1.65 ms = 0.00165 s

a = ?v/?t = [-60 sin35 -(+50)]/0.00165 = -51160.4 m/s^2

F = ma
