Homework Statement
A ball is thrown at 60deg with v(subzero) = 20 meters/sec to clear a wall that is 2 meters high. how far away is the wall?
Homework Equations
h=((v(subzero)*sin(theta))^2)/g
The Attempt at a Solution
I tried inserting my givens into the height equation and came up with a very funky answer. here 'tis:
h= ((20sin60)^2)/9.8=30.6
my answer key says x=1.2 or 33.5. I know I'd have to subtract 2 from the number I got, but that doesn't explain the discrepancy between my answer and the one the text gives. what am I doing wrong?
