What power output is required of a motor that needs to lift a 450 kg elevator car 12 meters in 8.0 seconds?\

Explanation:

Given

Required

Determine the power output required

First, we calculate the energy used to lift the object.

To do this, we make use of potential energy formula:

Where

So, we have:

The power output is then calculated as:

Convert to kilowatt

--- approximated

Hence, the power output is 6.62kw
