Question

A cyclist comes to a skiding stpo in 10m. During this process, the force on the cycle due to the road is 175N and is the opposite to the motion of the cycle.

(a) How much work does the road do on the cycle?

(b) How much work does the cycle do on the road? Why?

Answer 1

Dear Student ,
here in this question the , cycle and road will exhibit same force on each other according to Newton's third law of motion .
Now the work is done by the road on the cycle is , W = $10\times 175=1750J$
Again , the work is done by the cycle on the road is , W = $10\times 175=1750J$
