## Homework Statement

A motorcycle has an initial velocity of 8m/s, it increases it's speed to 17m/s, covering a distance of 30m in that time.

What is it's accleration? How long will it take to acclerate to 17m/s?

## Homework Equations

As stated in the equation

## The Attempt at a Solution

I faced this question on a quiz tonight and had not the slighest clue as to where to begin. I tried to gather a time for the change in speed over the distance, 17 - 8, / 30, which gave an answer of .3 seconds. I then tried plugging it into d = voT + 1/2 a t^2, to check if it was correct, but it wasnt. The value obtained was far too small.

This question really stumped me. In all the problems I have done before a time value was given. So, I had no idea how to approach it.

Thanks for your help
