Answer:

25 J

Explanation:

Using Law of Conservation of Energy

Total Energy before = Total Energy After

Potential Energy1 + Kinetic Energy1 = Potential Energy2 + Kinetic Energy2

Potential Energy1 + 0 = 0 + Kinetic Energy2

Potential Energy1 = [tex]\frac{1}{2}*m*v^{2}[/tex] =0.5*0.5*10*10= 25 J
