In the Soapbox Derby in (Figure 1), 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 63-ft-long (1 m = 3.28 ft) section tilted 15 ∘ below horizontal. Part A: 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. Part B: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
