Q.A projectile is fired horizontally from an inclined plane(of inclination 30 degree with horizontal)with speed 50m/s.If g=10m/s^2,the range measured along incline is

A)500m

B)1000/3m

C)200*root2m

D)100*root3m

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.
