I never know how to rearrange to find length or else
like I know how to rearrange ke=1/2mv2 to find the components in the equation but in exams they always ask calculate the length or time of flight how do I combine
l=d/v and ke=1/2mv2

1. l=d/v
2. Rearrange to get v=
2Ke= mv2 ……. 2Ke/m = v2 …square root(2Ke/m)=v

So I = d/(square root(2ke/m)
