13.3.21
A material point of mass m = 12 kg moves from a state of rest along a guide of radius R located in a horizontal plane. Determine the speed of the point at time t = 4 s after the motion begins, if it is acted upon by the force F = 22H, which forms a constant angle of 40 ° from the tangent to the trajectory of the point. (Answer 5.62)
