Physics

Explanation:

Begin by finding the acceleration with Newton's second law: F = ma.

10 = 2 * a => a = 5.0 m/s^2

Then use the "shortcut" velocity equation v^2 = u^2 + 2 a * x

v = $0^2 + \sqrt{2(5.0) * 1}$ = 3.16

Then use the equation for kinetic energy: k = $\frac{1}{2} mv^2$

k = $\frac{1}{2} * 2*3.16^2 = 9.9856J = 9.99J$
