Chapter 2, Problem 47PCE

A sled slides from rest down an icy slope. Measurements taken from a video show that the distance from the starting point to the sled at various times is as follows:

Time(s)	Distance from starting point(m)
0	0
0.50	0.36
1.0	1.3
1.5	3.2
2.0	5.7
2.5	8.8

(a) Plot the position of the sled versus time. (b) From your plot, determine the approximate average speed of the sled from t = 0.25 s to t = 1.3 s. (c) Determine the approximate acceleration of the sled, assuming it to be constant.
