How high was the top of the cliff above the water?

- Physics 124 -
**Steve**, Monday, September 17, 2012 at 5:14pmall we care about is the downward velocity. Initially that is

14.2 cos -36.9° = -11.36 m/s

so, starting from height H, the height after t seconds is

-11.36t - 4.9 t^2

at t=3.51,

h = -100.24 m

So, the cliff is 100.24m high
