Question

Mary applies a constant force of 25 N as she pushes a desk. In total, she moves the desk 12 m. How much work did Mary do?

A. 300 J
B. 325 J
C. 350 J
D. 375 J

Answer 1

The work done by Mary pushing the desk is calculated using the formula W = F × d, yielding 300 joules of work, which corresponds to answer choice A.

Step-by-step explanation:

The question involves calculating the work done by Mary when she applies a constant force to push a desk. To find the work done, we can use the formula W = F × d, where W is the work, F is the constant force applied, and d is the distance over which the force is applied. In this case, Mary applies a force of 25 N to move the desk by 12 m.

Therefore, the work done is:

W = 25 N × 12 m = 300 J.

So the correct answer is A. 300 J.
