The speed of an arrow fired from a compound
bow is about 57 m/s. An archer sits astride
his horse and launches an arrow into the air,
elevating the bow at an angle of 54
above the horizontal and 2.3 m above the ground.
What is the arrow's range?

1. time in air:
hf=ho+vi*sin54*t-4.9t^2

ho=2.3, hf=0
solve that above equation for time t.

Then, distancehorizontal
d=vi*cos54*time
