Please check the work so far and help me complete the practice problem

Sample exam I graphing problem A car moving along a straight road exhibits "stop-and-go" motion: it is initially traveling at 8 m/s for 3 s, slows at a constant rate over 4 s, stops, waits at rest for 1 s, then speeds up at a constant rate to 12 m/s over 6 s. a) Draw the velocity versus time graph. Be sure to label significant times and velocities on the appropriate axes. Velocity (m/s) Time (s) 7 8 13 b) Draw the acceleration versus time graph. Be sure to calculate the acceleration values. Acceleration (m/s?) Time (s) 3 7 8 13 c) Calculate the car's displacement over the entire time. 8 x3 = 24 A X = 24+ 16 + 36 2 ( 8 ) ( 4 ) = 16 DX = 76m - ( 6) ( 12 ) = 36 d) Plot the position versus time graph. 24- Position (m) Time (s) e) What was the car's average velocity over the entire time
