How to Find initial Velocity at 90 degrees with only a time variable given

[cloakblade5]

I am given the information that a nerf dart is launched upwards at a 90 degrees with the top of the launcher at 1.953ft and that it hits the ground .43 seconds later. I am then tasked with finding the initial velocity of the launcher and I have no idea where to start.

Welcome to PF cloakblade5,

You must have some idea as where to start, which concept(s) are involved? What are the relevant equations?
