Question

what is the formula of speed if the time is not given​

Answer 1

You may rearrange the following equation to do this:

$</p><p> {(Final Velocity) </p><p>\implies (Initial Velocity) + (Acceleration) \times (Time)}$

So in this case,

$\implies \mathtt(Time) = \frac{Final Velocity - Initial Velocity)}{(Acceleration)}$

Answer 2

You may rearrange the following equation to do this:

$\mathtt{{(Final Velocity) \implies (Initial Velocity) + (Acceleration) \times (Time)}(FinalVelocity)}</p><p>$

So in this case,

$\mathtt{(Time) = \frac{Final Velocity - Initial Velocity)}{(Acceleration)}}$
