A block of m1=2kg slides on a frictionless table with speed of 10m/s. In front of it anther block of mass m2=5kg is moving with speed 3m/s in same direction. A massless spring of spring constant k=1120N/M is attached on the backside of m2 .The max compression of the spring in cm when the blocks collide is

a) 25cm. B) 10cm. c) 2.5cm. d)5cm

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.
