a girl jumps off a high diving platform with a horizontal velocity of 2.77m/s and lands in the water 1.2s later the acceleration of gravity is 9.8m/s squared
how high is the platform and how far from the base of the platform does she land?

Physics 
Damon,
first do the vertical problem
We will have to assume she has no initial speed up, just horizontal
h = h initial + Vi t  4.9 t^2
0 = h initial + 0 (1.2)  4.9 (1.2)^2
solve for h initial
her horizontal speed never changed so horizontal distance is 2.77*1.
