if a small machine does 2500 joules of work on an object to move it a distance of 100 meters in 10 seconds, what is the force needed to do the work? What is the power of the machine doing the work?

Work done = force ×distance ; force = work done/distance  where workdone = 2500 J and Distance = 100 meters.  Force = 2500/100 = 25 Newtons Power = work done/time = 2500/10 = 250 Watts.
