# Calculating Power without distance?

## Homework Statement

Calculate the power of a motor that can lift 600 N in 1 Minute

## The Attempt at a Solution

I've been asked to help a friends daughter with this question because I work in a Lab, unfortunately I'm a biologist working in a chemistry lab so I'm struggling![/B]

I assumed that distance was required to work out power:

power (W) = N x Distance (m)

Time (s)

Am I missing something entirely?

Thanks in advance!

Hello AP, welcome to PF !

Yes, there is something missing: 600 N is a force. Work (energy) is force times distance. Power is work per time. So the calculation

Power = Force x distance / time
can't be made: the distance is missing.

Thanks very much!

This problem is in a GCSE revision book, and that is the problem word for word. At least it has got me interested in physics again, thanks for the welcome.

Strange. You can imagine it takes a bit more power to lift 600 N over 100 m in one minute than over 1 meter ...
