 Problem 12E

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 50.0 m/s, and it leaves the bat traveling to the left at an angle of 30° above horizontal with a speed of 65.0 m/s. If the ball and bat are in contact for 1.75 ms, find the horizontal and vertical components of the average force on the ball.

 Problem 12E

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 50.0 m/s, and it leaves the bat traveling to the left at an angle of 30° above horizontal with a speed of 65.0 m/s. If the ball and bat are in contact for 1.75 ms, find the horizontal and vertical components of the average force on the ball.

ANSWER:

Solution 12E

Step 1:

Data given

Mass of the ball  

Velocity before touching bat

Velocity after touching bat

Angle of ball

Time of contact

We need to find the horizontal and vertical component of average force on the ball

But we have momentum of the ball as

Before touching the bat
