An object of mass 2000 g possesses 100 J kinetic energy. The object must be moving with a speed of

If an object of mass 10 kg is moving with a uniform speed of 10 m/s, then the linear momentum and the kinetic energy of the object, respectively, are

If the linear momentum of a moving object gets doubled due to application of a force, then its kinetic energy will

The ratio of kinetic energies of two bodies of same mass is 4 : 9, the ratio of their velocities will be

There is a ball of mass 320 g. It has 625 J potential energy when released freely from a height. The speed with which it will hit the ground is

Weight and mass of an object are defined with Newton's laws of motion. Which among the following is true ?
