A climber pulls herself 8 meters upwards with a force of 150 Newtons. If it takes her 16 seconds to cover the 8 meters, how much power is she using?

Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.

The work done is force x distance
The power used is the rate of doing work, i.e. work/time
Note that the word for the unit of force, newton, has a lower case 'n' whereas the symbol has a capital 'N'. 
power=work/time=force*distance/time
