A car of mass m starts from rest and acquires a velocity along east v = vi (v > 0) in two seconds. Assuming the car moves with uniform acceleration, the force exerted on the car is
- mv/2 eastward and is exerted by the car engine.
- mv/2 eastward and is due to the friction on the tyres exerted by the road.
- more than mv eastward exerted due to the engine and overcomes the friction of the road.
- mv/2 exerted by the engine.
Answer
(B) mv/2 eastward and is due to the friction on the tyres exerted by the road.
