Question

What is the formula for finding the initial velocity when time and distance are given?

Answer 1

acceleration must be known too

Answer 2

yes. but what is the formula?

Answer 3

is this correct? Vi = (d-1/2at^2)/t

I'm not sure if I copied the right formula

Answer 4

2nd equation of motion
\[S=V _{i}t+\frac{ 1 }{ 2 }at ^{2}\]

Answer 5

it depends on the problem you have
you can sometimes use this formula:
Vi= 2d/t

Answer 6

what you just wrote above is the same one...simplified for Vi

Answer 7

provided we're talking about rectilinear motion
