Chapter 3, Problem 18P

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 55-ft-long section tilted 13º below horizontal.

Chapter 3, Problem 18P, In the Soapbox Derby, young participants build non-motorized cars with very low-friction wheels.

a. What is the maximum possible acceleration of a car moving down this stretch of track?

b. If a car starts from rest and undergoes this acceleration for the full 55 ft, what is its final speed in m/s?
