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 a–t, v–t,

and s–t graphs for each rocket until t = 20 s. What is the

distance between the rockets when t = 20 s?
