Solution 13.3.21 from the collection Kep OE 1989

The material point mass m = 12 kg moves from resting on the guide radius R, arranged in a horizontal plane. Determine at time points t = 4, the speed after the start of a movement when it is subjected to force F = 22 H, which forms a constant angle of 40 ° with the tangent to the trajectory points.
