A bullet of mass 25 g moving with a velocity of 200 cm/s is stopped within 5 cm of the target. The average resistance offered by the target is

A block of wood is placed on a surface. A force is applied parallel to the surface to move the body. The frictional force developed acts

The mass of a body is 2 kg. It weight is

A body is sliding down a rough inclined plane which makes an angle of 30 degree with the horizontal. If the coeffcient of friction is 0.26, the acceleration in m/s² is

A block of wood is placed on a surface. A force is applied parallel to the surface to move the body. The frictional force developed acts

Two bodies of masses 4 kg and 5 kg are acted upon by the same force. If the acceleration of lighter body is 2 m/s², the acceleration of heavier body is

Out of the basic forces , gravitational force

Inside the nucleus, two protons are held together by a force which overcomes the repulsion. This force is called

The force required to produce an acceleration of 2 m/s² on a mass of 2 kg is

A passenger in a moving bus is thrown forward when the bus is suddenly stopped. This is explained

A machine gun fires a bullet of mass 40 g with a velocity of 1200 ms-1. The man holding it can exert a maximum force on 144 N on the gum. How many bullets can he fire per second at the most?

A particle of mass 0.3 kg is subjected to a force F = -kx with k = 15 N/m. What will be its initial acceleration if it is released from a point 20 cm away from the origin?

A spherical ball of mass 10-6 kg hits a wall 1000 times per second normally with a velocity of 1000 m/s and rebounds with same velocity along the initial direction. The force experienced by the wall is

A passenger sitting in a bus moving at uniform speed, feels pushed backward whenever the bus is accelerated forward. This type of force is called

A body of mass 5 kg is travelling with a uniform velocity of 2 m/s. Its momentum is

A gun of mass 1000 kg fires a projectile of mass 1 kg with a horizontal velocity of 100 m/s. The velocity of recoil of the gun in the horizontal direction is

The mass of a body which is equal to the ratio of the force acting on a body to the acceleration produced in the body is

A block of mass 2 kg rests on a rough inclined plane making an angle of 30 degree with the horizontal. The coefficient of static friction between he block and the plane is 0.7. The frictional force on the block is
