kinetic energy: 10J

Explanation:

The kinetic energy of an object can be calculated with the formula:

color(blue)(|bar(ul(color(white)(a/a)color(black)(E_k=1/2mv^2)color(white)(a/a)|)))

ul("where"):
E_k=kinetic energy
m=mass
v=velocity

To find the kinetic energy, substitute your known values into the formula.

E_k=1/2mv^2

E_k=1/2(8kg)(5/2m/s)

E_k=color(green)(|bar(ul(color(white)(a/a)10Jcolor(white)(a/a)|)))
