If a small machine does 2,500 joules of work on an object to move it a distance of 100 meters in 10 seconds:

1. What is the force needed to do the work?
2. What is the power of the machine doing the work?

Well, 2500 joules for 100 meters is 2500/100=25 Newtons (force) 2500 joules in 10 seconds is a power of 250 Watts.

The force needed to do the work is equal to 25 N. The power of the machine doing the work is equal to 250 W.
What is power?
The power can be explained as the speed of doing work or work done in unit time. The SI unit of measurement of power joules per second (J/s) Watt (W).
Power can be defined as a** time-based parameter** and the change at work is done upon an object. The mathematical formula for power can be represented as mentioned below.
Power = Work/ time
P = W/t
Given, the **work done **by the machine, W = 2500 J
The distance moved by the object, d - 100 m
The** work done **can be represented in the form of the equation: W = F.d
2500 = F.100
F = 25 N
The power of the machine doing the work, P = W/t
P = 2500 / 10
P = 250 W
Therefore, the force required to do the work is equal to 25 N. The power of the small machine doing the work is equal to 250 W.
