A plane leaves the airport and flies 170 km at 68 degrees east of north and then changes direction to fly 230 km at 48 degrees south of east, after which it makes an immediate emergency landing in a pasture.

When the airport sends out a rescue crew, in which direction and how far should this crew fly to go directly to this plane?

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.
