1. A person pulls a block 2 m along a horizontal surface by a constant force F = 20 N. Determine the work done by force F acting on the block.
2. A block is pushed by a force of 200 N. The block’s displacement is 2 meters. What is the work done on the block?
3. The driver of the sedan wants to park his car exactly 0.5 m in front of the truck which is at 10 m from the sedan’s position. What is the work required by the sedan?

Answer:
1. 40 N-m or J
2. 400 N-m or J
3.
Explanation:
1.
Given:
F = 20N
d = 2m
Required: Work
Solution:
W = force x distance = 20N x 2m = 40 N-m
2.
Given:
F = 200N
d = 2m
Required: Work
Solution:
W = force x distance = 200N x 2m = 400 N-m
