A car moves along a straight section of road so that its velocity varies with time as shown in the graph below. a) Between t= 1 s and t = 5 s, does the car ever stop? Briefly explain. Greatest: t = Middle: t = Least: t = S S S velocity c) Assume the car starts at the origin (x=0 m), sketch the x vs t graph for this time interval on the axes below. Indicate appropriate values when necessary and units for the axes. 3 m/s 2 m/s 1 m/sh b) Think about the magnitude (size) of the car's acceleration at t = 1 s, t = 3 s, and t = 5 s. Rank, from greatest to least, the magnitudes of the accelerations at those three times. If two (or all three) of the accelerations are equal, note that as well.
