The answer is c. it requires no works
Answer:
c) is negative
Explanation:
As we know that work done by a force is the product of force and displacement vector.
W= F.d
F= Force
d= displacement
The work done by friction force always negative because it try to oppose the motion and act opposite to the direction of displacement.So the work done by air resistance is negative.
c) is negative
