ANALYSIS
1. Which has more kinetic energy:
a. A compact car going 70 mph or a tractor trailer going 15 mph?
b. An SUV going 30 mph or a pickup truck going 30 mph?
c. A school bus going 15 mph, an SUV going 35 mph, or a
compact car going 45 mph?

a) Tractor trailer will have more kinetic energyb) kinetic energy of pickup truck will be more than a SUV c) school bus will have the maximum kinetic energya) Tractor trailer will have more kinetic energy because its mass is way to heavy than that of compact car as kinetic energy is not only just dependent on velocity but also depend upon mass of that body .b) since , speed of SUV and truck is same , but mass of the truck is more than SUV , hence kinetic energy of pickup truck will be more than a SUV .C) Since , school bus carries number of passengers than SUV or compact car , hence school bus will have the maximum kinetic energy .To learn more about kinetic energy here :https://brainly.com/question/12669551#SPJ1
