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.

As much as you like except that the force required increases as the angle increases.
183.33... Watts.
Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts

power is required to do work and work efficiancy is the ammount of time it takes to do work.
Power is energy per unit time. So, the required power is 900/90 = 10 Watts.
Kinetic Energy
Yes; power= work/time, or work per time, measured in watts.
Decreases
As power = work done/time, power depends upon magnitude of w.d. and time required.
Calculate this in two steps. 1. Calculate the total work required. Reminder: work = force x distance. 2. Divide the work by the time to get the power.
The average power during the time interval.
