Assume the roller coaster starts from rest. Rank the velocities from greatest to least of the roller coaster at the 3 m mark (bottom of ramp), 16 m mark (top of 2nd hill), and the 12 m mark (top of the loop). Assume the roller coaster starts from rest. Rank the velocities from greatest to least of the roller coaster at the 3 m mark (bottom of ramp), 16 m mark (top of 2nd hill), and the 12 m mark (top of the loop). 3 m = 16 m = 12 m 16 m > 12 m > 3 m 3 m > 12 m > 16 m 3 m > 12 m = 16 m
