Question

A car of mass 1500 kg takes a turn of a curved road of radius 300m with a speed of 9 m/s. The centripetal
force acting on the car is

Options:

a) 45N
b) 225N
c) 810N
d) 405N​

Answer 1

d 405N should be a force acting on car

Answer 2

If Centripetal acceleration is Ca and Cnetripetal force is Cf

Ca = v^2 / R
Ca = 9^2 /300
Ca = 81/300
Ca = 0.27

F = ma
Cf = m * Ca
Cf = 1500 * 0.27
Cf = 405 N
