Answer:
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 [tex]v^2[/tex] = [tex]u^2[/tex]+ 2 a * x
v = [tex]0^2 + \sqrt{2(5.0) * 1}[/tex] = 3.16
Then use the equation for kinetic energy: k = [tex]\frac{1}{2} mv^2[/tex]
k = [tex]\frac{1}{2} * 2*3.16^2 = 9.9856J = 9.99J[/tex]
