Question

Помогите пожалуйста! Подъемник за 1 минуту перемещает груз массой 2у на высоту 40 метров. Определите мощность

Answer 1

T=1мин =60 c
m = 2 т  = 2000 кг
h  =40 м
N= ?
______________
N=A/t = Fh/t= mgh/t
N=2000*10*40/60=13333 Вт ≈13,3 кВт

Answer 2

Calculating Power for the Elevator

To calculate the power, we can use the formula:

Power = Work / Time

Where: - Work = Force × Distance - Force = Mass × Acceleration - Distance = Height

Given: - Mass (m) = 2u - Height (h) = 40 meters - Time (t) = 1 minute = 60 seconds

Calculating Force

The force can be calculated using the formula:

Force = Mass × Acceleration

Given: - Mass (m) = 2u

We need to find the acceleration to calculate the force.

Acceleration Due to Gravity

The acceleration due to gravity is approximately 9.81 m/s^2.

Calculating Work

The work done can be calculated using the formula:

Work = Force × Distance

Given: - Force - Distance (h) = 40 meters

Calculating Power

Now that we have the work and time, we can calculate the power using the formula:

Power = Work / Time

Let's calculate the power using the given values.
