The movement of a material point is described by the equations: x=At2, y=Bt, where A=1 m/s^2, B=2 m/s. Define: trajectory equation; point speed at time 1 s; the total acceleration of the point at that instant of time; the normal and tangential acceleration of the point at that moment.

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.
