Задача id4864

A body is thrown from a tower with a height H = 40 m with a speed v0 = 20 m/s at an angle α = 45° to the horizontal. Neglecting air resistance, determine: 1) time t of body movement; 2) at what distance s from the base of the tower the body will fall to the Earth; 3) the speed v of the body falling to the Earth, 4) the angle φ, which will be the trajectory of the body with the horizon at the point of its fall.
