1. A projectile was launched from the top of a 25-m high building at a velocity of +35 m/s and at an angle of 28° with the horizontal. (a) How far is the projectile from the building (horizontally) by the time it reaches its maximum height? (Ans.: 51.82 m) (b) If the projectile lands on a hill 3 meters high from the ground, how long was the projectile airborne? (Ans.: 4.38 s) (c) If the projectile lands on a hill 3 meters high from the ground, how far is the hill from the building? (Ans.: 135.32 m)
