If a bomb at rest explodes and splits into two equal fragments. These fragment will move in :

The momentum of a toy bus of 0.01 kg moving with a velocity of 5 m/s is

Two objects of masses 100g and 200g are moving along the same line and direction with velocities of 2 m/s and 1m/s respectively. They collide and after the collision, the first object moves with a velocity of 1.67m/s. Determine the velocity of second object ?

From a rifle of mass 4 kg,a bullet of mass 50 g is fired with an initial velocity of 35 m/s. Calculate the initial velocity of the recoil of gun ?

A bullet of 10 g strikes a sandbag at a speed of 10³ m/s and gets embedded after travelling 5 cm. Calculate the resistive force exerted by the sand on the bullet ?

Fundamental laws of the Newton's are called

Two person manage to push a motor car of mass 1200kg at a uniform velocity along a level road. The same motor car can be pushed by three person to produce an acceleration of 0.2m/s². With what force does each person push the motor car? (Assume that all the persons push the motor car with the same muscular effort). 

 The linear momentum 'p' of a moving body in one dimensional frame varies with time as p = x + yt², where x and y are position constants.The rate of change of momentum is the force that acts on the body. In such a case the force is :  

S.I unit of momentum is :
