An elevator lifts passengers 30m in 24sec. The power is 15,000W. What is the total weight of the elevator and passengers?

110,0000

How did you find that answer?

how much force is needed if the mass is 10kg the acceleration is 100m/50s2

anything that has mass and takes up space

the study of energy and matter

To find the total weight of the elevator and passengers, you need to use the formula:

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

First, let's calculate the work done by the elevator.

Work is given by the formula:

Work (W) = Force (F) * Distance (d)

Assuming a constant force is applied throughout, we can rewrite the formula as:

Work (W) = Weight (m * g) * Distance (d)

In this case, the distance (d) is given as 30 meters.

Now, we can substitute the values into the formula:

Work (W) = Weight (m * g) * Distance (d)
15000W = Weight * 30m

Next, we need to find the weight (m * g). The formula for weight is:

Weight (m * g) = Mass (m) * Acceleration due to gravity (g)

The acceleration due to gravity is approximately 9.8 m/s^2.

Now, let's rearrange the formula to solve for weight:

Weight (m * g) = 15000W / 30m

Weight (m * g) = 500W / m

Finally, we can substitute the given power value into the equation:

Weight (m * g) = 500 * 30
Weight (m * g) = 15000 Newtons

Therefore, the total weight of the elevator and passengers is approximately 15000 Newtons.
