The equation X(t) = 50 t + 15 t^2/T does not have to be derived with calculus. It is just the familiar equation X = Vo*t + (a/2)*t^2 In your case, Vo = 50 and a = (V2 - V1)/T The rest of the derivation can proceed without calculus.

No on the first. If you are in calculus, work= INT fdx=INT kxdx= 1/2 k x^2 eval at the limits .2 to .25 Same thing on the second. If you are not in calculus, the energy stored in a spring is 1/2 kx^2. You have to evaluate the stored energy at each point, and take the difference.

Are you doing pre-calculus or calculus? In calculus, the maximum is obtained by setting f'(t)=derivative with respect to t = 0 and solving for t. In pre-calculus, you can transform the expression by completing the squares. Ax² + Bx + C =A(x²+ (B/A)x + C/A) =A((x + (B...
