Displacement (s) of an object equals, velocity (u) times time (t), plus times acceleration (a) times time squared (t2). This means we use the chain rule, to find the derivative. Find the speed after \(\frac{p}{4}\) seconds. Then the speed of the particle is the magnitude of the velocity vector. We can find the acceleration functionfrom the velocity function by taking the derivative: as the composition of the following functions, so that.
