Question

A car of mass 1500 kg is moving with constant velocity 10 m/s. Calculate the force
required to move this car ? ​

Answer 1

Step-by-step 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.

∴     rmv2=μmg                         ⟹   μ=rgv2

μ=20×9.8(12.5)2=0.8
