SUVAT Solver в Android Market

SUVAT Solver (v. 0.1 Beta) Разработано Levs Ustinovs

This little tool resolves unknown SUVAT variables from at least 3 known ones.
SUVAT:
S - distance (m)
U - initial velocity (m/s)
V - final velocity (m/s)
A - acceleration (m/s^2)
T - time (s)

This is my first android app and second Java application, thus please don't judge...

Please post/email any suggestions, bugs etc..
