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.
Work (energy transferred) = force x distance = 200 N x 10 m = 2000 Joule. Power = work / time = 2000 Joules / 8 seconds = 250 Watts.
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
1 degree = 60 seconds. You now have all the information required to work out the answer to your question.
Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts

Power = Work divided by seconds.or in other words....Power = work/seconds.Clear explanation: Power is equal to:How much work is done (in joules) divided by the seconds of how much time did the work took.For example:Problem: A construction worker pushes the wheelbarrow with the power of 50 J per 2 seconds how much power does he use?Answer: 50 J divided by 2 s is 25 W so, the power is equal to 25 watts.
7.5 watts
27,000 J
Work (energy transferred) = force x distance = 200 N x 10 m = 2000 Joule. Power = work / time = 2000 Joules / 8 seconds = 250 Watts.
14.4
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 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
You need to convert the time to seconds. Then, if you divide the work (in joules) by the time (in seconds), you will get the power in watts.
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
