Лаг1989 задача №2.49
A ball of mass m = 0.1 kg, falling vertically from a certain height, strikes against the inclined plane and elastically jumps away from it. The angle of inclination of the plane to the horizon is α = 30⁰. The force pulse obtained by the plane during the impact time, F * Δt = 1,73 Ns. Find the time elapsed from the moment the ball hits the plane until it is at the highest point of the trajectory.
