3. Your friend's Frisbee has become stuck 16 m above the ground in a tree. You want to dislodge the Frisbee by throwing a rock at it. The Frisbee is stuck pretty tight, so you figure the rock needs to be traveling at least 5.0 m/s when it hits the Frisbee. (i) If you are at a horizontal distance 3 m from the tree and you release the rock 2.0 m above the ground, with what minimum speed must you throw it? Ignore the air resistance. (ii) Compute the throw angle(s) measured from the horizontal based on the minimum speed computed in (i).
