A 2 kg body and a 3 kg body are moving along the x-axis. At a particular instant the 2 kg body has a velocity of `3 ms^(-1)` and the 3 kg body has the velocity of `2ms^(-1)`. The velocity of the centre of mass at that instant is

A 2 kg body and a 3 kg body are moving along X-axis. At a particular instnat, the 2 kg body is 1 m from the origin and has a velocity of 3 ms^-1 and the 3 kg body is 2 m away from the origin has a velocity of -1 ms^-1 . Find the position and velocity of the centre of mass.

Two bodies of masses 3 kg and 4 kg are moving along X axis. At a time t, the bodics are at a distance of 2 m and 3 m from the origin and has velocities of 2 ms^(-1) and-3 ms^(-1) . Calculate the position and velocity of centre of mass. What will be the total momentum of the system?

A body of mass 20 kg is moving with a velocity of 2v and another body of mass 10 kg is moving with velocity V along same direction. The velocity of their centre of mass is

A body of mass 50 kg has a momentum of 3000 kg ms^(-1) . Calculate: The velocity of the body.

A force is applied on a body of mass 20 kg moving with a velocity of 40ms^(-1) . The body attains a velocity of 50ms^(-1) in 2 second. Calculate the work done by the body.

Two bodies of masses 4kg and 2kg are moving towards each other with 3ms^(-1) and 2ms^(-1) respectively. Then velocity of centre of mass is
