Two fully elastic objects of same mass is moving in same direction aiong straight line & collide with each other. Show that that they change velocity due to collision.

What is meant by elastic collision ? Show that when two bodies of equal masses moving in one dimension suffer elastic collision, their velocities are exchanged after collision.

Two particles start their journey at the same time from the same point following two straight lines inclined with each other at an angle theta . One moves with a uniform velocity u and other, starting from rest, moves with an acceleration a. show that the relative velocity between them will be minimum after a time u cos theta//a and its value is u sin theta .

If there by perfectly elastic collision between two bodies of the same mass moving along a straight line, the two bodies will

Two bodies, each having a mass of 3kg, collide with each other. One body was at rest and the other was moving with a 4 m cdot s^(-1) velocity. After collision they combine with each other. Find out the heat produced as a result of this collision. Mechanical equivalent of heat = 4.2 J cdot cal^(-1) .

Two parallel conductors carrying currents in the same direction attract each other-explain with reason.

Two spheres of the same mass move in the same direction , and the velocity of the first is double that the second. They collide head-on and lose 1/(18) th of their kinetic energy. Find the coefficient of restitution.
