An archer aims at a target 70 m away with diameter 1.22 m. The bull's-eye is 1.3 m above the ground. She holds her bow level at a height of 1.2 m and shoots an arrow with an initial velocity of 83 m/s.

a. What equations model this motion?
b. Will she hit the target? If not, by how much will she miss it?
c. At what range of angles could the archer hold her bow to hit somewhere on the target?
d. What initial velocity is necessary in order to hit the target if she holds her bow level?
