Solution K1 Option 64 from Reshebnik on theoretical mechanics manuals SM Targ 1982.
Check the condition of the task К1 (page 32 in the training manual Targ SM. 1982):
The point moves in the xy plane (Fig K1.0 - 1.9 K, K1 Table;.. The trajectory shown in the drawings point suspended). The law of motion defined by equations point: x = f1 (t), y = f2, where x and y are expressed in cm, t - in seconds.
It is necessary to find an equation for the trajectory of points in time t1 = 1 to determine the velocity and acceleration of the point, and its tangential and normal acceleration and a radius of curvature at the corresponding point of the trajectory.
Dependence x = f1 (t) labeled on the drawings, and the dependence y = f2 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
