A body A of mass 20 kg collides with another body B of mass 1 kg. then

A body of mass 4 kg collides elastically with another body of mass 2 kg at rest. If time of collision is 0.02 sec and average impulse force acted on each body is 100N, find the velocity of 4kg body before and after collision (Assuming collision takes place on a smooth horizontal surface)

A body of mass 4 kg is attached to another body of mass 2 kg with a massless rod. If the 4 kg mass is at (2i + 5j)m and 2 kg mass is at (4i + 2j)m, the centre of mass of the system is at (in m)

A body of mass 4 kg is attached to another body of mass 2 kg with a massless rod. If the 4 kg mass is at (2i + 5j)m and 2 kg mass is at (4i + 2j)m, the centre of mass of the system is at (in m)

A body of mass 30 kg attracts another body of mass 20 kg with force F. Find the value of F if distance between the centres of two bodies is 30 cm.

The weight of a body of mass 1 kg

A body of mass 3 kg collides elastically with another body at rest and then continues to move in the original direction with one half of its original speed. What is the mass of the target body?

A body of mass m kg collides elastically with another body at rest and then continues to move in the original direction with one half of its original speed. What is the mass of the target body ?
