Question

If a motorcyclist skids and stops after covering a distance of 15m the stopping force acting on motor cycle by the road is 100N then the wprk done by motorcycle on the road is

Answer 1

using W=F.S we get 100N×15m=1500Joules(or)N.m

Answer 2

Answer:I think it will be 0 Nm

Explanation: beause it says work done by the cyclist on the road..and the cyclist is skidding on the road thus he is not applying any force on the road

F=0

W=FscosA

Since F=0

W=0
