200J
Explanation:
Given parameters:
Force on boulder = 100N
Distance moved = 2m
Unknown:
Work done = ?
Solution:
Work done on a body is the force applied to move such body in the direction of the force.
Work done = force x distance
Input the parameters in the equation:
Work done = 100 x 2 = 200Nm or 200J
The work done in lifting the boulder is 200J
