Question

The position of a pinewood derby car was observed at various times;the results are summarized in the following table. Find the averagevelocity of the car for the following time periods. t (s) 0 1.0 2.0 3.0 4.0 5.0 x (m) 0 2.6 12.0 16.0 36.0 50.3 (a) during the first second
1 m/s

(b) during the last 3 s
2 m/s

(c) during the entire period of observation
3 m/s
I am having a problem on figuring out the problem. t (s) 0 1.0 2.0 3.0 4.0 5.0 x (m) 0 2.6 12.0 16.0 36.0 50.3 (a) during the first second
1 m/s

(b) during the last 3 s
2 m/s

(c) during the entire period of observation
3 m/s

Explanation / Answer

average velocity is x/t Part A) x/t=2.6/1=2.6m/s Part B) x/t=(50.3-12)/3=12.8 m/s Part C) x/t=50.3/5=10.1 m/s
