Physics projectile motion Problem?

ICEMAN asked:


The speed of an arrow fired from a compound
bow is about 31 m/s. An archer sits astride
his horse and launches an arrow into the air,
elevating the bow at an angle of 30? above the
horizontal and 2.6 m above the ground.
The acceleration of gravity is 9.81 m/s2 .

What is the arrow’s range?
Assume: The ground is level. Ignore air
resistance. Answer in units of m.

    well, i might be mistaken by not taking the 2.6 m into account.

    R = (v^2sin(theta))/ g
    R = 97.96 m

    89.12 m, including the 2.6 m height.

    GOGO has the wrong formula; it should be sin(2?) and the answer in that case is 84.8 m
