A boy throws a ball up into the air with a speed of 12.3 M/S the ball has a mass of 0.25 KG how much gravitational potential energy will the ball have at the top flight

18.9 J

Explanation:

The computation of the gravitational potential energy is shown below:

In this question,  we use the law of conservation of energy

As we know that

where

U = potential energy

And K = kinetic energy

h = 0

u = 0

Now placing given values to the above formula

As we know that

Total mechanical energy equivalent to potential energy

However, the mechanical energy is conserved, Ef = Ei, so

Therefore the potential energy at the top of the flight is

56 moles of   lieter in chemistry
