Then, we'd just solve the equation like this: ds/dt = -3t + 10. ds/dt = -3 (5) + 10. Recall that velocity is the first derivative of position, and acceleration is the second . Take another derivative to find the acceleration. Students should have had some introduction of the concept of the derivative before they start. The equation used is s = ut + at2; it is manipulated below to show how to solve for each individual variable. We use the properties that The derivative of is The derivative of is As such If the velocity is 0, then the object is standing still at some point. Substituting this expression into Equation \ref{3.19} gives, \[x(t) = \int (v_{0} + at) dt + C_{2} \ldotp\], \[x(t) = v_{0} t + \frac{1}{2} at^{2} + C_{2} \ldotp\], so, C2 = x0.
