A shell is fired vertically upwards with a velocity `v_(1)` from the deck of a ship travelling at a speed of `v_(2)`. A person on the shore observes the motion of the shell as parabola. Its horizontal range is given by:-

A shell is fired vertically upwards with a velocity v_(1) from a trolley moving horizontally with velocity v_(2) . A person on the the ground observes the motion of the shell as a parabole, whose horizontal range is

A shell is fired vertically upwards with a velocity v_(1) from a trolley moving horizontally with velocity v_(2) . A person on the the ground observes the motion of the shell as a parabole, whose horizontal range is

A body is projected vertically upwards with a speed v_(0) . Find the magnitude of time average velocity of the body during its ascent.

If the range of a gun which fires a shell with muzzle speed v is R, then the angle of elevation of the gun is

A shell is fired vertically from the earth with speed v_(esc)//N , where N is some number greater than one and v_(esc) is escape speed on the earth. Neglecting the rotation of the earth and air resistance, the maximum altitude attained by the shell will be ( R_(E) is radius of the earth):

If the range of a gun which fires a shell with muzzle speed V is R , then the angle of elevation of the gun is

If the range of a gun which fires a shell with muzzle speed V is R , then the angle of elevation of the gun is

If the range of a gun which fires a shell with muzzle speed V is R , then the angle of elevation of the gun is

If the range of a gun which fires a shell with muzzle speed V is R , then the angle of elevation of the gun is

A shell is fired vertically from a cannon which is travelling at constant speed u=30km/hr. the projectile leaves the connon with a velocity v_(r)=20 m/s relative to the cannon . Show that the shell will land on the vehicle at the gun location and calcu late the distance by the vehicle during the flight of shell.
