Hello. Answer is s=5.76m (how far the car travels when the driver slams brake on an inclined surface). I am uploading this question as the example answer's working out was so horrific I cannot follow through. I would like to see working out how the calculations equate to the answer being s=5.76m. Many thanks

Suppose you're converting a bill of materials for machining feedstock from the British gravitational (U.S. system) of units to International System (SI) units. Your goal is to have all of the material quantities in kilograms. Your bill of materials lists values for required weights of brass rod in pounds. To convert to these values to kilograms you first you divide by gravitational acceleration in feet per second squared to get a mass in slugs, then convert slugs to kilograms using standard conversion factors.
