Wilma nags Fred to go faster. He accelerates 3 m/s/s for 20 sec from a starting velocity of 20 m/s. He then drives at constant velocity for 20 seconds. He slows down at an acceleration of 2 m/s/s for 10 seconds. Graph the a vs t, v vs t, and d vs t plots for the trip. Find the final distance and speed.
Batman fires the Batmobile rockets. It starts from a velocity of 10 m/s and accelerates using the following relationship: a = 3 t + 4. He accelerates for 5 seconds and then drives at constant velocity for 5 seconds. Graph the a vs t, v vs t, and d vs t plots for her trip. Find the final distance and speed.
Wiley ties the insipid beeper to a rocket and fires him straight up at an acceleration = 50 t. After 3 seconds the fuel burns out. Graph the a vs t, v vs t, and d vs t plots for her trip. Find the max height and final speed.
Jackie Chan falls off a building which is 20 meters high. After 10 meters he hits an awning which slows him down with a constant acceleration = 15 m/s/s for .5 second. Then he falls the remaining 10 meters. Graph the a vs t, v vs t, and d vs t plots for the fall. Find the final distance speed.
