Product description
13.3.18
A material point of mass m = 16 kg moves in a plane along a curvilinear trajectory under the action of a resultant force F = 0,3t.
Determine the speed of the point at time t = 20s, when the radius of curvature of the trajectory? = 12 m and the angle between the vectors of force and velocity a = 50 °. (Answer 1.86)
