A 0.75 kg cart moves along a straight, horizontal track. The graph below shows the cart's velocity (VX) as a function of time (t). Velocity is given in units m/s, and time is given in seconds. Use this graph to answer questions a- e. V, (m/s) Velocity vs. Time On a Straight Horizontal Track 0.8 0.3 -0.2 -0.7 -1.2 t(s) 10 15 20 a) Indicate every time (t) for which the cart is at rest. b) Indicate every time interval for which the speed (magnitude of velocity) of the cart is increasing. Use evidence from the graph to justify your answers. c) Calculate the total displacement of the cart during the time interval t = 0 and t = 9. Show your work. d) Determine the horizontal position x of the cart at t = 9.0 s if the cart is located at x = 2.0 m at t = 0. Show your work.
