1) A plane's velocity increases from 40 m/s to 100 m/s over a 10 second interval. What is the plane's average acceleration for this interval? *

average acceleration = 6

Explanation:

Recall that the average acceleration  is defined by the change in velocity from an initial velocity , to a final velocity over the time (t) it took that change to happen. Then, in mathematical terms this is:

with our information this becomes:

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
