QUESTION:

Two rockets start from rest at the same elevation. Rocket A accelerates vertically at 20 m>s2 for 12 s and then maintains a constant speed. Rocket B accelerates at 15 m>s2 until reaching a constant speed of 150 m>s. Construct the at, vt, and st graphs for each rocket until t = 20 s. What is the distance between the rockets when t = 20 s?
