(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A cannon fires a 10.0kg cannon ball 1.0m above the ground and at 20^{o}to the horizontal with an initial speed of 100m/s. A castle 500m away has a wall 24.3m high. At what distance above the castle wall does the cannon ball pass?

2. Relevant equations

Δx = V_{i}t + 1/2at^{2}

It's the only one I can think of that applies.

3. The attempt at a solution

I thought of getting time it takes to get to the wall then using that to calculate displacement above the wall but I got the wrong answer. The only thing I don't know is how to include the mass (10.0kg) in my calculations.
