Question: In the Soapbox Derby, young participants build non-motorized cars with very low-friction wheels. Cars race by rolling down a hill. The track at Akron's Derby Downs, where the national championship is held, begins with a 55ft-long section tilted 13deg. below horizontal.
Part I: What is the maximum possible acceleration of a car moving down this stretch of track?
Part II: If a car starts from rest and undergoes this acceleration for the full l, what is its final speed in m/s?
I need help to solve the above question.
