How Far Will the Ball Travel Horizontally If Aimed at 33 Degrees?

[schrock]

I am convinced I have not received enough info to solve this prob. Please help me get started. A small steel ball bearing with a mass of 20.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.35 m. Calculated the horizontal distance the ball would travel if the same spring were aimed 33.0 degrees from the horizontal.

My guess is that you have to assume the spring has no internal inertial so that all of the spring force goes into accelerating the ball. Since it's not included, the problem statement implies that the spring constant doesn't affect the outcome.
