When the two bodies of equal mass collide head on elastically, their velocities are mutually exchanged.

(ii) If m₁ = m₂ and u₂ = 0 then

v₁ = -u₁ and v₂ = 0

PLS EXPLAIN THIS ( WHEN A BODY COLLIDES WITTH A BODY OF SAME MASS AT REST......THEN THE 1st BODY must STOP and 2nd BODY MUST MOVE WITH A VELOCITY OF THE PREVIOUS BODY)

CORRECT ME IF I AM WRONG!!! PLS

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
