  • A car of mass m starts from rest and acquires a velocity along east, v - vhat(i) (v gt 0) in two seconds. Assuming the car moves with uniform acceleration, the force exerted on the car is

    A
    `(mv)/(2)` eastward and is exerted by the car engine.
    B
    `(mv)/(2)` eastward and is due to the friction on the tyres exerted by the road.
    C
