The coefficients of friction between a race car’s tyres and the track surface are 0.950 for static friction and 0.800 for kinetic friction. The car is on a level circular track of radius 50.0 m on a planet where g = 2.45 m/s2 compared to Earth's g = 9.80 m/s2 . Compare the maximum safe speed for the race car on the track on the planet and the maximum safe speed on Earth. (ie. compare the maximum speeds that the race car can go around the track without slipping)

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
