Задача 11066.

A material point of mass m = 11 kg moves along a curvilinear trajectory under the action of a resultant force F = 20Н. Determine the speed of the point at the time when the radius of curvature of the trajectory is 15 m and the angle between the force and the velocity vector is 35 °.

A detailed solution with a brief record of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, please write. I try to help.
