Homework Statement
"A ball rolls off an incline plane. The speed of the ball is 22m/s and the plane is inclined at 32 degrees to the horizontal.If the incline is 9.0m above the ground, how far from the base of the incline will the ball hit the floor?" (The rounded answer is supposed to be 11m)
There is also a diagram that goes with this question, which I have attached a picture of.
Homework Equations
Cosθ, sinθ, or tanθ?
The Attempt at a Solution
The rounded answer is supposed to be 11m.
The closest answer I got to this was 10.6126...m which I accidentally got by 9/(cos32). After thinking it over, I realized that I was calculating the length of the ball's vertical path (according to my understanding of the diagram. I drew what I believed to be the correct diagram and attached it, but I don't think it is right anymore.) I'm mostly confused about the placement of the 32° because, from my understanding, I think it has to be placed at another part of the diagram, other than on the roof.
Thank you in advance!
