I've been trying to come up with the answer but it hasn't gotten me anywhere.

I know that I need to find the angle to get the velocity.

delta X = 48.76 m

delta Y = -30.48 m

t = 5 s

Vi

I know that I need to find the angle to get the velocity.

**Q:**A rock is projected from the edge of a 30.48 m tall building at some unknown angle above the horizontal. 5 seconds after, the rock strikes the ground at a distance of 48.76 m from the building. Determine the speed of the rock.**Given:**delta X = 48.76 m

delta Y = -30.48 m

t = 5 s

**Find:**Vi
