(DAL 01001 1 H .1. Velocity (mfs) ._i -|--ll'\\Jl'\\Jm 0010010019 i 0"" 2 h 4 A student drops a rock from the top of a cliff such that the rock falls downward toward Earth's surface in the absence of air resistance. The downward direction is considered to be the positive direction. The graph shows the rock's velocity as a function of time. Which of the following methods should be used to determine the total distance traveled by the rock after 45? A. Use the maximum value of the curve, as it states that the rock traveled 40 meters in 1 second, which means that the rock traveled 160 meters in total. B. Use the area under the curve, as it states that the rock traveled 80 meters in total. C. Use the slope of the curve, as it states that the rock traveled 10 m/ S in 1 second, which means that the rock traveled 40 meters in total. D. The answer cannot be determined unless a graph of the object's position as a function of time is given
