Question

iv. The lift raises a car of mass 850 kg to a height of 2.1 m. It uses a force of 8330 N and takes 4 seconds to raise the car. What is the power of the lift? (1 point)

Answer 1

Power is 4373.25 W

Step-by-step explanation:

We have,

The lift raises a car of mass 850 kg to a height of 2.1 m. It uses a force of 8330 N and takes 4 seconds to raise the car. It is required to find the power of the lift. Power is equal to the rate at which the work is done. So,

`P=(Fd)/(t)\\\\P=(8330* 2.1)/(4)\\\\P=4373.25\ W`

So, the power of the lift is 4373.25 W.
