(Solved): A projectile is thrown from the edge of a 120m cliff with an initial velocity of 140m/s at an ...
A projectile is thrown from the edge of a cliff with an initial velocity of at an angle of with the horizontal (figure below). Neglecting air resistance, find: (a) The horizontal distance from the edge to the point where the projectile hits the ground; (h) The greatest elevation above the ground reached by the projectile; (c) When the greatest elevation is reached; (d) The velocity of the projectile just before touching the ground.
