Question

.Find the given relation independent of t.
vf=vi+at
S=Vit+1/2at?​

Answer 1

Answer:

ou now know two formulae that relate the initial speed, Vi, the final speed, Vf, the distance, d, the acceleration, a and the time, t.

When you are solving a problem where you need to find one of these variables but you are lacking another one, you should combine the two formulae to eliminate the unknown variable. Here is a list of the combinations you can use when not given a variable:

Not Given Formula to eliminate that variable

( not needed )

d a = ( Vf - Vi ) / t

a d = 1/2 ( Vf + Vi ) × t

Vf 2d / t = at + 2Vi

Vi 2d / t = -at + 2Vf

t 2da = Vf² - Vi²
