A rocket burns 0.5 kg of fuel per second ejecting it as gases with a velocity of 1600 m//s relative to the rocket . How much force is exerted on the rocket ? Also , calculate the velocity attainted by the rocket , when its mass reduces to (1)/(200) th of its initial mass .

A body of 5kg is moving with a velocity of 20m/s. If a force of 100N is applied on it for 10 s in the same direction as its velocity, what will now be the velocity of the body?

. The mass of a ship is 2 xx 10^7 kg. On applying a force of 25 xx 10^5 N, it is displaced through 25 m. The speed of ship is

The force acting on a body of mass 10 kg is (2 overset ^i +j -overset ^k ) N. If the body is initially at rest, then velocity at the end of 20 sec will be
