Physics problem involving two snowballs?

  1. Jun 20, 2010 #1
    Snowballs are thrown with a speed of 13 m/s from a roof 7.0 m above the ground. Snowball A is thrown straight downward; snowball B is thrown in a direction 15 degrees above the horizontal. Find the direction of motion of the two snowballs just before they land.
    theta A = ? and theta B = ? degrees to the horizontal.

    For the equations I tried Ymax = Vo^2(sin theta)^2 / 2g, and Yfinal = Yo + VoyT +.5ayT^2, but they obviously didn't work or else I wouldn't be on here.

    I'm honestly just confused on this problem. It looks relatively easy but I'm just stuck.

    Lets start with the easy one:
    If snowball A is thrown straight down, what are the velocities in the x-direction Vx(horizontal) and the y-direction Vy (vertical) initially?
