13.3.4
Within a smooth tube curved along a circle of radius R = 2 m, in a horizontal plane a material point with mass m = 42 kg moves under the action of the force F = 21 N from the rest state. Determine the horizontal component of the reaction of the tube at time t = 7 s, if the direction Force coincides with the velocity vector. (Answer 257)
