A student drives a moped along a straight road as described by the velocity versus time graph in the figure. (a) Sketch a graph of the position versus time, aligning the time coordinates of the two graphs. (b) Sketch a graph of the acceleration versus time directly below the velocity-time graph, again aligning the time coordinates. (c) What is the acceleration (in m/s2) at t = 7.0 s ? m/s2 (d) Find the position relative to the starting point (in m) at t = 7.0 s. m (e) What is the moped's final position (in m) at t = 9.0 s ? m
