First mulitiply Newton x meter to get the energy (or work) required. Then divide the result by the time to get the power.
Power is energy per unit time. So, the required power is 900/90 = 10 Watts.
Since power is defined as Work divided by time, and work is F x d. W = 110 x 20 W = 2200 J P = 2200 / 8 = 275 Watts
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
Power=(Force X distance) / (time) P= (13N x 3m) / (5 sec) P= 7.8 Watts
1 minute = 60 seconds. You now have all the information required to answer the question.
