A particle starts from rest at A and moves with uniform acceleration a metre per second square in a straight line. after (1/ a) seconds a second particle starts from A and moves with uniform velocity u in the same line and same direction. if u is greater than 2 metre per second then during the entire motion second particle remains ahead of the first particle for a duration?

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.
