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.

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 of mass 6 kg is fired from a gun of mass 600 kg. If the recoil velocity of the gun is 3 m/s , find the muzzle velocity of the shell.

A stone is thrown by a student from the bottom of a hill with a velocity 30 ms^(-1) making an angle of 60^(@) with the horizontal. If the slpe of the hill is 30 ^(@) with the horizontal. Find the distance from the student to a point at which the stone fals on hill, use g= 10 ms^(-2) .

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.
