Two particles, A and B of masses m and 3m, are moving along X and Y axes respectively, with the same speed v. They collide at the origin, and coalesce into one body, after the c ollision. What is the velocity of this coalesced mass ?

Two particles A and B of masses m and 2m are moving along the X-axis and Y-axis respectively with the same speed v. They collide at the origin and coalesce into one body, after the collision. What is the velocity of this coalesced mass? What is the loss of energy during this collision?

Two bodies of masses m and 2m are moving along positive x and y axes respectively with equal speed 4 ms^-1 . They collide at origin and stick together. The final velocity of combined mass is

A body A of mass 5kg is moving along the x-axis with a velocity 2m/s. Another body (B) of mass 10 kg is moving along the y-axis with a velocity sqrt(3)m//s . They collide at the origin and stick together. What is the final velocity of the combined mass?

Two bodies A and B of masses m, and m, moving with velocities V_(1) and V_(2) respectively collide. If m_(2) gt m_(1) then the force exerted by B on A during the collision is
