Activity 2. A hunter observed a bird flying overhead and estimated the height at 15m and its speed at 20 m/s. His rifle is capable of a muzzle velocity of 48 m/s. If he fires at the instant the bird is directly overhead, at what angle should he incline his rifle in order to hit it? How many meters from his position will the bird hit the ground assuming that the weight of the bullet compared to the weight of the bird is negligible?
