Calculating average acceleration

Question

Using the data, calculate the average acceleration for the following intervals:

i.             From t = 0 to t = 45

ii.            From t = 25 to t = 45

iii.           From t = 40 to t = 45

table of data

t in seconds 

0             5             10             15              20           25            30            35             40          45

v(t) in feet per second       

274.27     233.19     179.23        141.4       108.83     80.80       56.68       35.91        18.04       2.65
