The 2.7 kg cylinder B and 1.8 kg wedge A are released from a bigger triangular wedge A wich is fixed. the angle of inclination of A is 30 degrees frm the horizontal.Assuming that cylinder rolls without sliding on the wedge A and neglecting the friction between A and C determine (a) the acceleration of wedge (b) the angular acceleration of cylinder (g=10m/s^2)

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.
