Question
A car takes a turn with a velocity of 50 ms-1 on the circular road of a radius of curvature of 10 m. calculate the centrifugal force experienced by a person of mass 60 kg inside the car?
Solution
Given,
Mass of a person = 60 kg
The velocity of the car = 50 ms-1
Radius of curvature = 10 m
Centrifugal force F = `(mV^2)/r = (60 xx (50)^2)/10` = 15,000 N
