Question

A student drives a moped along a straight road as described by the velocity versus time graph in the figure. The divisions along the horizontal axis represent 5.0 s and the divisions along the vertical axis represent 4.0 m/s. Sketch this graph in the middle of a sheet of graph paper. (Do this on paper. Your will need it to do part (a) and (b).)

(a) Directly above your graph, sketch a graph of the position versus time, aligning the time coordinates of the two graphs. (Do this on paper. Your instructor may ask you to turn in your work.)

(b) Sketch a graph of the acceleration versus time directly below the velocity-versus time graph, again aligning the time coordinates. On each graph, show the numerical values of x and ax for all points of inflection. (Do this on paper. Your instructor may ask you to turn in your work.)

(c) What is the acceleration at t = 30.0 s?
1_________ m/s^2 ???????

(d) Find the position (relative to the starting point) at t = 30.0 s.
2_____________m ????

(e) What is the moped's final position at t = 45.0 s?
3 _____________m ??????

Explanation / Answer

where is the graph???
