Question

09:04 P1 P1.pdf 4 Distance and speed (20 pts) A cart on a track starts at position 0. Then at time 0, the back end of the cart is sharply tapped or it, suddenly creating a steady speed equal to 2 m s. At time-2s, the cart is again sharply tapped, creating a steady speed equal to 4 m/s. At time 4s, the cart is again sharply tapped, creating a steady speed equal to 6 m/s Finally, a speed of 8 m/s is achieved after a final tap at tme-6s. (Assume friction can be neglected.) The resulting graph of speed versus time is shown below. Draw an accurate graph of the cart's position versus time in the empty space below. Hint: your graph should be a sequence of (connected) straight lines that change slope at the three times the cart is tapped 0 1 2. 34 67.
