A particle of mass m moving with velocity V_o strikes a simple pendulum of mass m and sticks to it. The maximum height attained by the pendulum will be

If a shell fired from a cannon, explodes in mid air, then

A body is moving with a velocity v, breaks up into two equal parts. One of the part retraces back with velocity v. Then, the velocity of the other part is

Two trolleys of mass m and 3 m are connected by a spring. They were compressed and released once, they move off in opposite direction and comes to rest after covering distances S₁ and S₂ respectively. Assuming the coefficient of friction to be uniform, the ratio of distances S₁ : S₂ is

In which case does the potential energy decrease?

A sphere of mass in, moving with velocity V, enters a hanging bag of sand and stops. If the mass of the hag is M and it is raised by height h, then the velocity of the sphere was

Two bodies of masses m and 2m have same momentum. Their respective kinetic energies E₁ and E₂ are in the ratio

If a lighter body (mass M₁ and velocity V₁) and a heavier body (mass M₂ and velocity V₂) have the same kinetic energy, then

Two bodies with kinetic energies in the ratio of 4 : 1 are moving with equal linear momentum. The ratio of their masses is

If the water falls from a dam into a turbine wheel 19.6 m below, then the velocity of water at the turbine is (g = 9.8 m/s²)
