Normal Force: Solution
A force of 60 N is used to drag a sled 5 m across the ground.
The force is directed at an angle upward from the sled as shown in figure.
Question: What is the work done by the horizontal component of the force?
- 180 J
- 200 J
- 190 J
- 20 J
- 0 J
The horizontal component of force is 40 N and is in the direction of motion.
W = F × d = (40 N) ×(5m)
= 200 J.
