Product description
13.3.13
A material point of mass m = 18 kg moves in a horizontal plane along a curvilinear trajectory under the action of the force F = 25Н.
Determine the radius of curvature of the trajectory at the time when the velocity of the point v = 4 m / s, and the velocity and force vectors form
The angle between them is 55 °. (Answer 14.1)
