Two masses m1 and m2 are released from side of a prism having base angles 30 and 60 respectively. What is the relative velocity of m1 with respect to m2 after 5 secs

a. 50/ 3^1/2

b. 50

c. 50* 3^1/2

^{d. 5}

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.
