of 30 m in a time of 2 s is 15 m/s.

I have a whole bunch of problems such as these and i'm not sure what math formula to use to figure problem.I know its Acceleration !

change of velocity

time interval

!

"v

"t

but how do I work it out

**Damon**, Wednesday, October 10, 2012 at 1:34pmaverage speed = distance / time

= 30 m / 2 s

= 15 m/s

It is CHANGE in velocity / time
