phase 1
v = 5 t , slope up of 5 up to Vi = 25
phase 2
v = constant = 25 from t = 5 to t = 20
phase 3
v = 25- 5(t-20), slope down of -5
A car accelerates from rest at 5 m/s2 for 5 seconds. It moves with a constant velocity for some time, and then decelerates at 5 m/s2 to come to rest. The entire journey takes 25 seconds. On a separate sheet of paper, plot the velocity-time graph of the motion. Describe the shape of the graph here.
