1. A Fiat and a Porsche drive down the freeway. At the instant you measure, the Porsche is traveling at 65 mph and the Fiat is traveling at 50 mph.
True or False: The acceleration of the Porsche must be greater than the acceleration of the Fiat at the same moment.
Explain your answer using words AND a velocity graph (sketch a reasonable/realistic velocity vs time for both cars on the same graph)
2. Watch the attached video
A zebra drinks from a watering hole and is ambushed by a crocodile. What’s more important and why: the zebra having a high maximum speed or a high acceleration?
