Can someone help break this down.. Please tell me if what I identified is so far correct. Also what equations should I use???

x1= 10m
x2=?
v1= 1.2 m/s
v2=?
a= -9.8 m/s^2
t= ?

a) How long before the diver hits the water?
b.) At what horizontal position from the end of the diving board does he hit the water?
c.) What is the diver's velocity just before hitting the water?
