5. A particle is moving with uniform acceleration along a straight line AB. Its speed at A and B are 2m/s and 14m/s respectively. Then [a] its speed at the midpoint is 10m/s [b] its speed at point P such that AP:PB is 1:5 is 4m/s [c] the time to go from A to mid point of AB is double to move from mid point to B
[d] none of the above.

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.
