Answer:
U = 1000 J
Explanation:
By the conservation of energy, potential energy is converted into kinetic energy when the ball falls from a height.
[tex]U = \frac{1}{2} mv^2 = mgh[/tex]
U = Energy (in Joules)
m = mass (in kg)
v = velocity in (m/s)
g = acceleration due to gravity (in m/s^2)
h = height (in m)
Let's use [tex]mgh[/tex] as we have the values given.
[tex]U = 2(10)(50)[/tex]
[tex]U = 1000 J[/tex]
