Question

Suppose you exert a 25 N force to lift a ball 0.4 m in 2 s. How much work is done?

A. 5 J
B. 62 J
C. 10 J
D. 20 J

Answer 1

The work done is 10 J.

Step-by-step explanation:

To calculate the work done, we can use the formula Work = Force x Distance. In this case, the force exerted is 25 N and the distance moved is 0.4 m. So the work done is:

Work = 25 N x 0.4 m

Work = 10 J

Therefore, the correct answer is C. 10 J.
