In the Soapbox Derby, young participants build non-motorized cars with very low-friction wheels. Cars race by rolling down a hill. Assume that the track begins with a 49-ft-long (1 m = 3.28 ft) section tilted 14° below horizontal.
What is the maximum possible acceleration of a car moving down this stretch of track?
Express your answer to two significant figures and include the appropriate units.
If a car starts from rest and undergoes this acceleration for the full L, what is its final speed in m/s?
Express your answer using two significant figures.
