I need help figuring out how to approach a problem. I need to determine the initial velocity of an object for it to be at a specific height at a specific time. For example, what would the initial velocity of an object need to be for it to be at 38.7m @ 4.7 seconds if thrown straight up from the ground (launched up at 90 degrees)? If I understand correctly, there could be two answers, one for the initial trip up and the other for the way down. I tried using d=Vo * t + 1/2a * t^2 plugging in the variables I have to solve for Vo but my answer doesn't check out. Intuitively it seems like I am going to need to be able to figure out how to calculate what the velocity would need to be for it to be at 38.7 m @ 4.7 seconds on the downward motion. Either way, what formula should I be using here? If you can, please show the steps you took to work it out because I need to understand this so I can apply it to the actual question.
