Question

A student drives a moped along a straight road as described by the velocity versus time graph in the figure. (m/s) f (s) (a) Sketch a graph of the position versus time, aligning the time coordinates of the two graphs. x (m) x (m) x (m) t (s) r (s) r (s) 10 t (s) 10 (b) Sketch a graph of the acceleration versus time directly below the velocity-time graph, again aligning the time coordinates. a (m/s') a (m/s') a(m/s2) a (m/s) t (s) r (s) t (s) r (s) (c) What is the acceleration (in m/s) att- 7.0 s (d) Find the position relative to the starting point (in m) at t 7.0s 34 Your response differs from the correct answer by more than 10%. Double check your calculations. m (e) what is the moped's final position (in m) at t-9.0 s? 28 Your response differs from the correct answer by more than 10%. Double check your calculations. m

Explanation / Answer

From the graph of x-t which you have selected as being correct, at 7 s the position of the moped is 70 m.

From the same graph the position of the moped at t = 9s, is 80 m.

Hence the answers are 70 m and 80 m.
