DESCRIPTION
10347.
A car of mass m = 1 t moves along a horizontal section of the road. The path traveled by him changes according to the law s = At Bt ^ 2, where A = 1 m / s; B = 1 m/s^2. At what point in time t will the engine power be equal to N = 70 kW, if the resistance force in this case turns out to be equal to Fc = 12 kN?
