Title: Physics: if you want to calculate the average speed?
Post by: ayoubi on June 03, 2009, 10:37:25 am

v+u/2 right?
does v means the last speed
u means 0 for example .. the starting point?

if der r 2 speeds given den u can add dem n divide by 2 to find da avg speed but otherwise da formula is avg speed=total distance travelled/ total time taken.... ;)

n da equation u mentioned id (v-u)/t wer v=final velocity
                                                        u=initial velocity
                                                        t=time taken
but this is 2 find da acceleration.....

hope u understud n ur confusion cleared.....Take care...all da best 4 da xam! ;) :)

(v+u)/2
