Question

Определите мощность, которой должен обладать двигатель, чтобы поднять груза за 5с при работе 1500Дж.

Answer 1

P=A/t
P=1500/5=300 Вт

Answer 2

Calculating the Power Required to Lift a Load

To calculate the power required to lift a load in a given time, we can use the formula for power:

Power (P) = Work (W) / Time (t)

Where: - Work (W) = 1500 J (as given in the question) - Time (t) = 5 s (as given in the question)

Using the given values, we can calculate the power required.

Calculation

Power (P) = Work (W) / Time (t)

Power (P) = 1500 J / 5 s

Power (P) = 300 Watts

Therefore, the power required for the engine to lift the load in 5 seconds while doing 1500 J of work is 300 Watts.
