In Denver, children bring their old jack-o-lanterns to the top of a tower and compete for accuracy in hitting a target on the ground. Suppose that the tower height is h = 7.80 m, and that the bulls-eye's horizontal distance is d = 3.3 m from the launch point. (Neglect air resistance.) 

If a jack-o-lantern is given an initial horizontal speed of 3.3 m/s, what are the direction and magnitude of its velocity at the following moments in time? (Let the +x axis point to the right.) 
(a) 0.75 s after launch
 ° (below the +x-axis)
  m/s

 (b) just before it lands 
 ° (below the +x axis)
  m/s
