A particle is located at coordinates x = 2.0 m, y = 3.0 m. What is the magnitude of the torque about the origin when the particle is acted upon by a force of magnitude 5.0 N in (a) the positive x direction, (b) the positive y direction, and (c) the negative x direction?

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.
