Question

anna started down the slope at 2m/sec. five seconds later, her speed was 17m/sec.what was her average acceleration?

Answer 1

3
`(m)/(s) ^(2)`

Step-by-step explanation:

You can use the formula for average acceleration which is a =
`(v)/(t)`. The v in this case is change in velocity. To find change in velocity you get final velocity subtract by the initial velocity. In this case this gets you 17 - 2 which gets you 15 m/s. You can then plug these into the equation to get 15/5 which is 3.
