6. In a competition, Mike lifts a 100 kg weight from the floor in 2 sec. Brian also
zaharov [31]

Answer:

Explanation:

Analogy:

Who does more work:

Work done is defined as the product of force and distance. Work is done when force moves a body in a particular direction.

In this case, work done is the same thing as the potential energy of the weight.

           Work done = potential energy = m x g x h

 Mass of weight = 100kg for both Mike and Brian

g is the acceleration due to gravity

h is the height

Since they lifted the weight through the same height;

        Work done by Mike = 100gh

        Work done by Brian = 100gh

Both Mike and Brian does equal work

Who generates more power:

Power is the rate at which work is done;

          Power  = \frac{Work done}{time}

Power generated by Mike = \frac{100gh}{2}  = 50gh

Power generated by Brian = \frac{100}{3} = 33.33gh

We can see that Mike generated more power
