Homework Equations
The Attempt at a Solution
I attempted to first finding h by using the conservation of energy Potential(intial)=Kinetic(final) and i came out with 1.033m. let me know if i was right. The main problem is the second part. I'm drawing a blank to find the angle with only one component. Maybe I am missing something. Thank u in advanced
