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

A ball of mass M and speed of V collides head on with a ball of mass 2M and a speed of v/2, as

pogonyaev

Answer:

2/3V

Explanation:

Given that a ball of mass M and speed V collides with another ball of mass 2M and velocity v/2 . After collision they stick together and we need to find their speed after collision . According to Law of Conservation of Momentum , The total momentum of the system before and after collision is constant .That is ;
