The height of a rocket, launched from the ground, is given by the function y=30t-5t^2, where y is in meters and t is in seconds. An observer is sitting at ground level a distance d from the launch point. If r is the distance between the observer and where the rocket is, show that dr/dt= (30t-5t^2)(30-10t)/sqrt(30t-5t^2)^2 + d^2. Show all your work.
