SUMMARY

The discussion focuses on rearranging the equation Δy = V₀t - 1/2 gt² for the variable T. The correct approach involves recognizing the equation as a quadratic in the form of at² + bt + c = 0. By applying the quadratic formula, T can be solved accurately. The final rearrangement leads to T = [V₀ ± √(V₀² - 2gΔy)] / g, which provides the necessary solutions for T based on the initial velocity V₀ and the change in height Δy.

Homework Statement


I need to rearrange the following equation for T. I haven't done this for so long, that it has slipped my mind.


Homework Equations


change in y = Voy t - 1/2 g t2


The Attempt at a Solution


t = (change in y + 1/2) / (Voy - g)

I know this is completely wrong, but I can't, for the life of me, figure it out. :/

So you have Δy= v0t-1/2gt2

this can be written as 1/2gt2-v0t+Δy = 0

doesn't this look similar to at2+bt+c=0?

now apply the quadratic equation formula.
