Just use v = a x t, where a is the acceleration of gravity (g)

Trying to find u given she catches it at the same height, therfore:
v=-u a=-g and t=2.6
Using v=u+at it will simplify to u=-2.6g/-2.
Taking g as 10ms^-2 u=13ms^-1

Closing this old thread as the OP has graduated to the major leagues now and is no longer interested in throwing balls straight up.

Thank you all for your comments and contributions here.
