A student drives a moped along a straight road as described by the velocity-versus-time graph in Figure P2.54. Sketch this graph in the middle of a sheet of graph paper.
(a) Directly above your graph, 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 vx-t graph, again aligning the time coordinates. On each graph, show the numerical values of x and ax for all points of inflection.
(c) What is the acceleration? at t = 6 s?
(d) Find the position (relative to the starting point) at t = 6 s.
(e) What is the moped’s final position at t = 9 s?
