A body of mass 60 kg is dragged with just enough force to start moving on a rough surface with coefficients of static and kinetic friction 0.5 and 0.4 respectively.On applying the same force what is the acceleration? a..98 m/s2 b.9.8 m/s2 c. .54 m/s2 d 5.292m/s2

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.
