Your instructor will walk at constant velocity beneath the announcer's booth of the varsity baseball field (a two-story tower). Your teammate will stand tall on top of the announcer booth's steps, with her or his dropping hand raised above his/her head. The egg must freefall to strike the helmet of the instructor.

What equation of motion would I use here? Just x=1/2at^2+vt?

d instructor = u t
find t so you can find d, how far the instructor is from directly under when you drop.

H = height
H = (1/2) g t^2
t = sqrt (2 H/g)

so d = u sqrt (2 H/g)
