Give the magnitude and direction of the net force acting on
a car moving with a constant velocity of 30km/h on a rough road

Text Solution

Verified by Experts

Force is being applied to overcome the force of friction . But as velocity of the car is constant , it acceleration . A = 0 . Hence net force in the car F = ma = 0
