...7 m/s. Person B is standing...? 1. Person A sprints around a circular track of radius 100m at a constant speed of 7m/s. Person B is standing at a distance 200m from the center of the track. How fast is the distance between the 2 changing when the distance between them is 200m?
2. Show that the volume of the sphere is decreasing at rate proportional to its surface area then the radius of the sphere is shrinking at a constant rate.
