Average acceleration given velocity points?

[syeh]

How do you find average acceleration given a table with points of velocity (ft/sec)?

t (sec): 0 15 30 45 60
v(t) (ft/sec):0 40 60 70 75

the question asks: Find the average acceleration of Rocket A over t=[0,60] seconds.


I used change in v(t)/change in time to find 4 points of acceleration (2.667, 1.333, .667, .333). I added those and divided by 4 to get 1.25. But I do not think that is how to solve the problem.

You just find the quotient (v(60)-v(0))/(60-0). That's average acceleration.
