Target version K1 98, reshebnik Targ SM 1983

Solution of the K1 version 98 of Reshebnik termehu Targ SM 1983.
CHECK condition to the problem K1 (p. 18-20 on the training manual Targ SM 1983): Point B moves in the xy plane (Fig K1.0-K1.9, K1 table, the trajectory shown in the figures in terms of probation..). Set point law of motion equations: x = f1 (t), y = f2 (t), where x and y are expressed in cm, t - in seconds. Find the equation of the trajectory; at time t1 = 1 to determine the velocity and acceleration of the point, as well as its tangential acceleration and the radius of curvature at the corresponding point of the trajectory. Dependence x = f1 (t) labeled on the drawings, and the dependence y = f2 (t) is given in the Table. K1 (for Figs. 0-2 in column 2 to Fig. 3-6 in column 3 for the Fig. 7-9 column 4).
