A motorcycle of mass 100kg moves round in a circle of radius 10m with a velocity of 5 ms-1. find the coefficient of friction between the road and the tyres.

A motorcycle of mass 100kg moves round in a circle of radius 10m with a velocity of 5 ms-1. find the coefficient of friction between the road and the tyres.

Answer Details

F = (mv)2/r = (100 x 5)2 = 250N R = mg = 100 x 10 - 1000N coefficient of friction, µ = (F)/R = (250)/1000 = 0.25
