A 900 kg car moving at `10 ms^(-1)` takes a turn around a circle with a radius of 25 m. Determine the acceleration and the net force acting upon the car.

Text Solution

Verified by Experts

When the car turns around circle, it experiences centripetal acceleration `a=upsilon_2/r`
`a=(10)^2 / 25 =100/25 " " therefore a=4 ms^(-2)`
Net force acting upon the car ,
F= m a = 900 x 4 = 3600 N
