Question

A `900` `kg` car moving at `10` `ms^-1` takes a turn around a circle with a radius of `25.0` `m`. What is the acceleration and the net force acting upon the car?

Answer 1

The centripetal acceleration is given by `a=v^2/r=10^2/25=4` `ms^-2`

Using Newton's Second Law, the centripetal force acting is `F=ma=900*4=3600` `N`
