WebBut in answer to the question itself, yes, you can apply the quadratic formula anytime you have a quadratic expression, so y2 +2ty+t2 +1−C et = 0 ... Kinetic Energy with constant … WebAug 16, 2004 · Since F (x) is linear, you are finding the area of a triangle with base (x) and height (-kx). So, (Work done by F)= (1/2) (x) (-kx). Since that force is conservative, the potential energy is minus the work done by that force. So, U=- (- (1/2)kx^2)= (1/2)kx^2. Aug 15, 2004 #9 Nenad 698 0 chroot said:

WebNow, as aΔt = Δv we have ΔE ≈ mvΔv But where does the factor 1 2 come in? From basic calculus: Δ(v2) = (v + Δv)2 − v2 = 2vΔv + (Δv)2 ≈ 2vΔv which yields ΔE ≈ 1 2mΔ(v2) = Δ(1 2mv2) and thus E ≈ 1 2mv2 + const If we go from finite to infinitesimal time intervals, the equations become exact and we no longer need to assume a constant force.
