A gun fires a bullet. The barrel of the gun is inclined at an angle of `45^@` with horizontal. When the bullet leaves the barrel it will be travelling at an angle greater than `45^@` with the horizontal. Is this statement true or false?

A bullet is fired with speed 50m//s at 45^(@) angle with horizontal. Find the height of the bullet when its direction of motion makes angle 30^(@) with the horizontal.

A railway flat car has an artillery gun installed on it. The combined system has a mass M and moves with a velocity V . The barrel of the gun makes an angle a with the horizontal. A shell of mass m leaves the barrel at a speed v relative to the barrel. The speed of the flat car so that it may stop after the firing is

A car has a gun mounted on it. The combined system has a mass 10m and moves with a velocity V. The barrel of the gun makes an angle 37° with the horizontal. A shell of mass m leaves the barrel at a speed 50 m/s relative to barrel in the forward direction. The speed v of the car so that it may stop after the firing is
