Questions: 1. A snowball is launched off a roof that is 5.0 m high. Its initial velocity is 10.0 m/s at an angle of 30 above the horizontal. Neglect air resistance. What is the distance in the snowball travels in the x-direction when it lands on the ground at an altitude of 0.0 m. Follow the following two steps. a) Find the time of flight of the snowball. (You'll need to use the quadratic equation. Use the smallest positive time. Remember than negative times don't make any sense.) b) Find the horizontal distance the snowball travels
