Answer:
The amount of work Lee did is 2.0 × 10³ J
Step-by-step explanation:
Hi there!
The work done on an object by a force applied in the direction of movement can be calculated with the following equation:
W = F · d
Where:
W = work done on the object.
F = applied force on the object.
d = distance traveled by the object.
In this case, we know that the force that Lee applies is 68 N and this force is applied constantly during the displacement of 30 m.
Then, applying the work equation:
W = 68 N · 30 m
W = 2.0 × 10³ J
