Two bodies of mass `m_(1) = 1kg` and `m_(2) = 2kg` move towards each other in mutually perpendicular directions at velocities `v_(1) = 3m//s` and `v_(2) = 2m//s` (Fig). As a result of collision, the bodies stick together. Determine the amount of heat Q liberated as a result of collisions.

Two bodies of masses 1 kg and 2 kg are moving in two perpendicular direction with velocities 1 m//s and 2 m//s as shown in figure. The velocity of the centre of mass (in magnitide) of the system will be :

Two bodies of masses 1 kg and 0.5 kg move towards each other with velocities 10 cm *s^(-1) and 5 cm *s^(-1) respectively . After collision, the bodies coalesce (join together). Find the common velocity after collision and the loss in kinetic energy.

Two bodies of masses 0.1 kg and 0.4 kg move towards each other with the velocities 1 m/s and 0.1 m/s respectively, After collision they stick together. In 10 sec the combined mass travels

Two blocks, with masses m_(1) 2.5 kg and m_(2) = 14 kg , approach each other along a horizontal, frictionless track, The initial velocities of the blocks are v_(1) = 12.0 m//s to the right an d v_(2) = 3.4 m//s to the left. The two blocks then collide and stick together. Which of the graph could represent the force of block 1 on block 2 during the collision ?
