A car is traveling at 60 mi/hr. Over the past 3 seconds, it has been increasing its speed at a rate of 4 mi/hr. If 4 more seconds pass by, what will be the speed of the car?
What is 76 mi/hr.
400
Fluid friction acting on a falling object
What is Air Resistance.
400
How would the passengers move if they were suddenly run into from behind in a car?
What is Move Backwards because an object at rest wants to stay at rest.

You are in a car moving at 60 miles/hour. Your friend tosses a penny into the air. If you slammed on the brakes while the penny was in the air, how would the penny move and why?
What is Fly forward into the windshield at 60 miles/hour because unbalanced forces acted on the car not the penny.
