a bullet is to be fired with speed of 20m/s to hit a target 200m away on a level ground. If g=10m/s^2, the gun should be aimed

Hi,

Time taken by bullet to cover 20 m horizontally = (20/200) = 0.1 s
Distance covered by bullet vertically in that time = s = 0.5 * 10 * 0.1²= 0.05 m
So, the bullet should be fired 5cm above the target.

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.
