Using the velocity graph determine the cart’s average acceleration from 1.0 s to 3.0 s.
Would it be fair to say the cart had a constant acceleration? If so, how is this apparent?
Determine the area under the curve on the velocity graph in order to find the displacement.
Use the position graph to find the displacement and compare to the previous result – it should
be same.
Answers for Fan Cart:
1. a = 0.15 m/s2, 0° (or 0.15 m/s2, East)
2. Starting at about t = 0.4 s the data shows a fairly consistent linear pattern – however, on close inspection it appears to curve slightly downward. Therefore we can say the acceleration is roughly constant and does not vary much, but it does appear that the acceleration decreases slightly as the speed increases.
3. ½ bh = ½ (3.05 s)(0.48 m/s) = 0.73 m, 0º
4. xf – xi = 1.24 m – 0.48 m = 0.76 m, 0º The two values are essentially the same, allowing for error.
