Mr. Yaz's science class got on the magic school bus and traveled to Mr. Yaz's brain to obtain all the info needed to dominate the semester exam! The bus traveled 360 meters and arrived at the brain in 60 seconds. What was the bus's speed? As the bus arrived at the brain it came to a stop in 3 seconds. What was the bus's acceleration? Now DOMINATE the final! :)
v = 6 m/s; a = -2 m/s2
