A body is dropped from height 'h'. If the coefficient of restitution is 'e', calculate the height achieved (h1) after one bounce.

If the values of each of length, mass and time are doubled, then the work done becomes

A body of mass m₁ moving at a constant speed undergoes an elastic collision with a body of mass m₂ initially at rest. The ratio of the kinetic energy of mass m₁ after the collision to that before the collision is

A thin uniform metallic triangular sheet of mass M has sides AB = BC = L as shown in the figure. What is its moment of inertia about axis AC lying in the plane of the sheet?

A body floats in a liquid contained in a beaker. The whole system falls freely under gravity. The upthrust on the body due to the liquid is

A body of density ρ is dropped from rest at a height 'h' into a lake of density 'σ', where σ>ρ . Neglecting all the dissipative forces, calculate the maximum depth to which the body sinks before returning to float on the surface.

If the Earth stops rotating, the value of g at the equator will

Two particles of masses m and 4 m have kinetic energies in the ratio 2 : 1. What is the ratio of their linear momenta?

Kepler's second law states that the straight line joining a planet to the sun sweeps out equal areas in equal time. This statement is equivalent to the statement that
