1. (01.07 HC) A 50 kg cart moves on a straight horizontal track. The graph below shows the velocity of the cart (VX) as a function of time (t). Velocity is given in units m/s, and time is seconds. Vx (m/s) Velocity vs. Time of 50 kg Cart On a Straight Horizontal Track 1.0 0.8 0.6 0.4 0.2 0.0 t(s) 10 15 20 -0.2 -0.4 -0.6 -0.8 -1.0 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. Justify why you selected those time interval(s). c. Determine the horizontal position x of the cart at t = 9.0 s if the cart is located at x = 1.0 m at t = 0. Show your work. d. Use the velocity versus time graph in this question to create an acceleration versus time graph for the cart. Using a sheet of graph paper, create the acceleration (a) versus time (t) graph for the motion of the cart from t = 0 to t = 25 s. Write your name and today's date in the upper right corner. Scan or take a picture of your graph and attach it to this item.

4. A computer animator is trying to make an animation of a rabbit rushing back and forth along a sidewalk. He decides to model the rabbit's velocity over time as shown in the following graph, where time is measured in seconds and velocity is measured in meters per second. velocity 3 2 1 777749 -24 -4 -5 3 4 8 9 time 10 (Here, positive velocities indicate that the rabbit is heading east; negative velocities indicate that the rabbit is heading west.) (a) Suppose the rabbit starts at a position we'll call 0. Sketch a rough graph of the rabbit's position as a function of time on the interval [0, 10]. We do not expect your graph to be perfect, but it should accurately show whether the graph is increasing or decreasing and whether it is concave up or concave down. (b) At time 0, there was a squirrel sitting 2 meters east of the rabbit. Suppose that the squirrel's velocity on [0, 10] is given by the same graph shown above. On your graph from (a), also sketch the squirrel's position as a…
