Question
An archer defending a castle is on a 15.5 m high wall. He shoots the arrow straight down at 22.8 m/s. How much time does it take to reach the ground
Answers
using the "free fall" equation ... h = -1/2 g t^2 + vo t + ho
0 = -1/2 * 9.81 * t^2 - 15.5 t + 22.8
use the quadratic formula to find t
0 = -1/2 * 9.81 * t^2 - 15.5 t + 22.8
use the quadratic formula to find t
