Задача 10839.

The time dependence of the rate of the first material point V1 = (at2 + bt) i + yt ^ 3j (m / s), the second law of motion of a material point r2 = yt ^ 4i-at ^ 3j (m). At time t = 1c acceleration points turned perpendicular to each other. At what ratio between the constants is that possible?

Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
