You throw a snowball horizontally from the roof of a building that is 71.0 m above flat ground. The snowball hits the ground a distance of 45.0 m from the base of the building. Assume free fall with up as positive y-direction, and use g = 9.80 m/s2. Take the initial direction of motion of the snowball to be the positive x-direction.
(a) How long does the projectile remain in the air?
(b) What is the initial speed of the snowball?
(c) What is the vertical component of its velocity as it strikes the ground?
(d) What is the snowball's speed just before it hits the ground?
(e) In what direction is the snowball moving just before it hits the ground? 5° (anti-clockwise from the positive x-direction)
