Problem: A car moving at 20 mi/hr can stop on a wet surface in a minimum distance of 50 ft.
Part A: What is the minimum stopping distance if the car moves on the same wet surface at 80 mi/hr?
I need tutor help to solve the above problem and assume the stopping acceleration is the same in both cases.
