The distance between two places A and B on road is 70 kilometer A car starts from A and the other from B. If they travel in the same direction, they will meet after 7 hours. If they travel towards each other they will meet after 1 hour then find their speed?

Places A and B are 30 km apart and they are on a straight road.Hamid travels from A to B on bike. At the same time Joseph starts from B on bike and travels towards A. They meet each other after 20 minutes. If Joseph would have started from B at the same time but in the opposite direction (instead of towards A), Hamid would have caught up with him after 3 hours. Find the speed of Hamid and Joseph.

A body A moves with a uniform acceleration a and zero initial velocity. Another body B starts from the same point, moves in the same direction with a constant velocity v. The two bodies meet after a time t. The value of t is

Paranali and Prasad started walking to the East and to the North respectively, from the same point and at the same speed. After 2 hours distance between then was 15sqrt(2) km. Find their speed per hour.

A body of mass 2 kg travels with a velocity of 8 m//s makes a head on collision with another body having mass 4 kg, which is travelling in the same direction with a velocity of 1 m//s . Calculate the velocities of the two bodies after collision. Find the loss in kinetic energy of the system. (Given e = 0.5)
