Vi=25m/s

Theta=25.8511 degrees

x=50m

t=2.22s

and of course g=9.81m/(s^2)

"How high does the rock fly in the air?"

I know this problem should be a simple plug and solve but my answer does not match the one in the back of my book which is 6.05m. Test coming up and I want to know how to reach that answer or if the book is wrong, what the right answer is.

Please show steps and what equation to use.

**fairness**, Wednesday, October 6, 2010 at 11:19am25sin25.8511 = 10.90

t=2.22 is the total time

2.22/2= 1.11 is half the time

h=vit . 1/2 at^2

h=(10.9*1.11) -1/2*9.8*(1.11^2)

h=6.06
