Question

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? *

​

Answer 1

average acceleration = 6
`(m)/(s^2)`

Step-by-step explanation:

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

`a=(v_f-v_i)/(t)`

with our information this becomes:

`a=(v_f-v_i)/(t) = (100-40)/(10)=6\,(m)/(s^2)`
