A gun mounted on the top of a moving truck is aimed in the backward direction at an angle of 30 degrees to the vertical.If the muscle velocity of gun is 4m/s, the value of speed of truck that will make the bullet come out vertically is
firstly, you should concentrate on terms '' muzzle velocity'' and ''aimed in''.Muzzle velocity means velocity WITH RESPECT TO the gun and aimed in means angle made by bullet as seen from truck...
to find velocity of truck that will make bullet come out vertically(as seen from ground frame ), velocity of truck must be equal to horizontal component of velocity of bullet wrt truck i.e 4cos(90-30)=2 m/s......
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.
