Displacement (m) b. The displacement with respect to time for a conveyer belt is shown in Figure 2. Use this graph to sketch a graph of the belt's velocity. This sketch should only be rough, but on it you should clearly label i. the times where the speed is zero ii. the three times where the speed is a local maximum There is no need to add a numerical scale to the vertical-axis, it is the shape of the curve that is important. 70 60 50 40 30 20 10 0 0 100 200 300 400 500 600 700 800 900 1000 1100 1200 -10 -20 -30 -40 -50 Time (s)
