A snowball is thrown horizontally with a speed of 23.9 m/s from the top of a campus building. It takes the snowball 1.91 sec to travel from the top of the building to the parking lot below. How tall is the building?

  1. h=1/2 g (1.91)^2

  2. If I was to need to find the range of the snowball how would I go about doing that
    ?
