Velocity of a body at t=0 is (10)^1/2 in north east direction and it is moving towards south with accceleration of 2 m/s2. the magnitude of velocity and DIRECTION of body after 5 sec willl be-

10 m/s towards east, 10 m/s towards north, 10m/s twrds south , 10m/s twrrds north east.

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.
