An air track like the one shown in Figure 4-2 has a block with a height h = 12.0 cm under one support. The other support is 3.50m away. What is the angle of inclination y? According to Equation 5, the component of acceleration parallel to the track is a = g sin y where g = 9.80 m/s2. For this value of y what is a? Show your work.
