86. The motion of a mass of m = 0,25 kg is described by the equation r = Asinωti + Acosωtj, where A = 2 m; ω = 0,7 rad / s; i, j - the unit vectors of the coordinate axes x and y. Determine path s, the passed point in time t1 = 8, and the force F, acting on the point at the end of said time interval.
