a) Draw a velocity-time graph to represent the motion of Trevor's car. b) Convert Trevor's initial velocity into km/hr. Is he travelling above the speed limit? c) Calculate Trevor's acceleration from 5s to 10s and from 20s to 30s. d) Determine Trevor's displacement from 0 to 35 seconds. Please show all formulas used and all work. Thanks!

2. Trevor is driving north along a street with a posted speed limit of 60 km/h. He notices an unmarked van parked along the curb and assumes that it is a photo-radar unit. The statements below show the changes in Trevor's velocity AFTER he notices the van. i) He travels at a constant velocity of 20.0 m/s [N] for 5.0 seconds ii) He decelerates from 20.0 m/s [N] to 10.0 m/s [N] for 5.0 seconds iii) He travels at a constant velocity of 10.0 m/s [N] for the next 10.0 seconds iv) He accelerates to a constant velocity of 15.0 m/s [N] over a period of 10.0 seconds v) He maintains his velocity at 15.0 m/s [N] for 5.0 more seconds
