Answer to Problem 10STP

Work done on the ball is 2.1 J_ .

Explanation of Solution

Given:

Force applied on the ball = 4.2 N

Distance travelled by the ball while it is in the hand = 0.50 m

Distance travelled by the ball after it leaves the hand = 8.5 m

Formula used:

Work done is given by,

W=Fd

Where F is force and d is distance.

Calculation:

Work will be done on the ball only while the ball is in contact with the hand.

Work done is calculated as,

W=Fd   =(4.2 N)(0.50 m)   =2.1 J

Conclusion:

Work done on the ball is 2.1 J_ .
