9.8 m/s^2. Answer in units of m

- Physics -
**Steve**, Thursday, November 29, 2012 at 11:45amthe vertical component of the initial velocity is 13.8 sin59° = 11.83 m/s

the horizontal component is

So, the height y is 7.11 m/s

since the rock hit 20.3 m away, it fell for 20.3/7.11 = 2.855 sec

h + 11.83*2.855 - 4.9*2.855^2 = 0

h = 6.165 m
