Test driver at incredible motors is testing a new model car with a speedometer calibrated to read m/s rather than mile/h. the following series of speedometer readings was obtained during test run
along the long straight road
T[s] 0 2 4 6 8 10 12 14 16
V[m/s] 0 0 2 6 10 16 19 22 22
[a] Compute the average acceleration during each 2 second time interval. Is acceleration constant
? Is it constant during any part of the test run?
[b] make acceleration time graph for the data above. From the graph find instantaneous
acceleration at t=9s, t=13s and t=15s
