Задача 10311.

The point moves in a circle so that the path is determined by the equation: S=A Bt^2, where B= 0.1 m/s^2. After 1.6 s after the start of the movement, the tangential acceleration became equal to the normal one. Find the radius of the circle.

A detailed solution with a brief note of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
