You throw a snowball horizontally from the roof of a building that is 74.0 m above flat ground. The snowball hits the ground a distance of 45.0 m from the base of the building. Take up to be positive y-direction, and use g = 9.80 m/s2. Take the initial direction of motion of the snowball to be in the positive x-direction.
(a) How long does it take for the snowball to hit the ground after you throw it?
(b) What is the initial speed of the snowball? (HINT: is this horizontal or vertical?)
(c) What is the vertical velocity as it strikes the ground? (would the velocity be positive or negative?)
(d) What is the resultant of snowball's speed just before it hits the ground? (HINT: we have a horizontal and a vertical velocity, how can we combine two vectors that are at right angles to each other?)
