True or False. A body at rest may possess energy.

The temperature of a solid object is observed to be constant during a priod. In the period (i) Heat may have been supplied to the body (ii) heat may have been extracted from the body (iii) no heat is supplied to the body (iv) no heat is extracted from the body

A body of mass m, moving with velocity mu collides elasticity with another body at rest having mass M. If the body of mass M moves with velocity V, then the velocity of the body of mass m after the impact is

A lighter body collides with much more massive body at rest. Prove that the direction of lighter body is reversed and massive body remains at rest.

A body of rest mass m_0 collides perfectly inelastically at a speed of 0.8c with another body of equal rest mass kept at rest . Calculate the common speed of the bodies after the collision and the rest mass of the combined body .

A body of rest mass m_0 collides perfectly inelastically at a speed of 0.8c with another body of equal rest mass kept at rest . Calculate the common speed of the bodies after the collision and the rest mass of the combined body .
