There are three particles ABC which are situated at vertex of equilateral triangle

ABCof side d at time T = 20 each of the particle moves with constant speed v always has its velocity along a b be always has be always has MC always has its velocity along CA at what time they will meet with each other

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.
