can you please tell me the solution of question no. 18 of HC vERMA on page 50. in which amass is being pulled from two sides by strings passing over through pulley. at centre the angle made by strings is 2theta. find the velocity of block

ans given u/cos theta.

pleaaaase help

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.
