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

Car start from rest mean initial velocity u=0, also and t=2s mass is given as m.

As we know so

Now force exerted on the car i.e. here this force is due to engine of car so whatever this force is actually internal force in another words due to friction force the car moves in eastward direction.

Therefore, option (b) is correct.
