A cannon on a level plane is aimed at an angle `theta` above the horizontal and a shell is fired with a muzzle velocity `v_(0)` towards a vertical cliff a distance D away. Then the height from the bottom at which the shell strikes the side walls of the cliff is

A cannon on a level plane is aimed at an angle alpha above the horizontal and a shell is fired with a muzzle velocity v_(0) towards a vertical cliff a distance R away. Then the height from the bottom at which the shell strikes the side walls of the cliff is

A cannon of mass 5m (including a shell of mass m) is at rest on a smooth horizontal ground, fires the shell with its barrel at an angle theta with the horizontal at a velocity u relative to cannon. Find the horizontal distance of the point where shell strikes the ground from the initial position of the cannon :-

A small ball thrown at an initial velocity v_(0) at an angle alpha to the horizontal strikes elastically with a smooth vertical wall moving towards it at a horizontal velocity v and returns to the point from which it was thrown. Determine the time t from the beginning of motions to the moment of impact with vertical wall. Neglect friction losses.

A target situated on a hill can be seen from the foot at angle alpha above the horizontal .The distance of the target along the horizonal is R. if a shell is fired from the foot at an angle beta with the horizontal, find the velocity required for it to strike the target.
