An 800-kg car moving at 20m/s takes a turn around a circle with a radius of 12.2 m.
Determine the acceleration and the net force acting upon the car.

Sagot :

a = 32.79 m/s²

F = = 26,232 N

Further explanation

Given

mass = 800 kg

velocity = 20 m/s

r = 12.2 m

Required

The acceleration

The net force

Solution

Circular motion :

a = v²/r

a = 20²/12.2

a = 32.79 m/s²

The net force⇒Centripetal force

F = mv²/r

F = 800 kg x 32.79 m/s²

F = 26,232 N
