Question

An object of mass 8.5 kg is kept on a level surface. On applying a force of 60 N, the object moves 12 m in the direction of the force. Calculate the quantity of work done.

• A. 102 J
• B. 720 J
• C. 60 J
• D. 510 J

Answer 1

Answer:

B. 720 J

To calculate the work done, we use the formula:

Work Done (W) = Force (F) x Distance (d)

Given:

F = 60 N
d = 12 m

W = F x d
= 60 N x 12 m
= 720 J

Therefore, the quantity of work done is 720 Joules.
