Question

A walrus accelerates from 7.0km/h to 34.5km/h over a distance of 95m.  What is the magnitude of the walrus's acceleration?

anonymous · Answer

$$ Average\ Acceleration  = \frac{ Change\ In\ Velocity}{Change\ In\ Time} $$

Simply written as:

$$ A_{avg} = \frac{\Delta V}{\Delta t} $$

Do you know what Velocity is equal to?

NO

anonymous · Answer

As an equation I mean. Do you know the equation for Average velocity?

anonymous · Answer

Well don't I have to convert 7.0km/h and 34.5km/h to m/s?

anonymous · Answer

Okay, average velocity is just like acceleration, except with it is your change in *distance* over change in time.

$$ V_{avg} = \frac{\Delta x}{\Delta t} $$

Yes you do

Okay but I do not have a time in this problem

Im really new to this stuff and I absolutely can not grasp the stuff. Could you possibly show me exactly what to do
