mass 1500 kg is moving along a circular road of radius 150 m with a maximum speed of 15m/m without skidding. find(1)force of fiction (2) coefficient of friction between tyres and road​

Answer» EXPLANATION:Given :         Radius of the circular PATH         r=20  m                     Mass of the car        M=1500kg                     Speed        v=12.5  m/s Let the coefficient of friction be  μ. The centrifugal FORCE will balance the friction force so that the car does not SLIP. ∴       r mv  2  ​   =μmg                         ⟹   μ=  rg v  2  ​    μ=  20×9.8 (12.5)  2  ​   =0.8
