A cannot fires from under a shelter inclined at an angle `alpha` to the horizontal (Fig.). The cannot is at point A at a (distance l from the base of the shelter (point B). The initial velocity of the shell is `v_(0)`, and its trajectory lies in the plane of the figure. Determine the maximum range `L_(max)` of the shell.

A projectile, thrown with velocity v_(0) at an angle alpha to the horizontal, has a range R. it will strike a vertical wall at a distance R//2 from the point of projection with a speed of

A cannon of mass M starts sliding freely down a smooth inclined plane at an angle alpha to the horizontal. After the cannon covered the distance l , a shot was fired, the shell leaving the cannon in the horizontal direction with a momentum p. As a consequence, the cannon stopped. Assuming the mass of the shell to be negligible, as compared to that of cannon, determine the duration of the shot.

A shell is fired from a gun from the bottom of a hill along its slope. The slope of the hill is alpha = 30^(@) , and the angle of the barrel to the horizontal beta = 60^(@) . The initial velocity u of the shell is 21 ms^(-1) . Find the distance from the gun to the point at which the shell falls.

A shell is fired from a gun from the bottom of a hill along its slope. The slope of the hill is prop = 30^@ and the angle of the barrel to the horizontal beta = 60^@ . The initial velocity v of the shell is 21 m s^-1 . Then find the distance of point from the gun at which the shell will fall.

An inclined plane making an angle beta with horizontal. A projectile projected from the bottom of the plane with a speed u at angle alpha with horizontal, then its maximum range R_("max") is
