This is the problem:
I have a marble launcher that is 1.17 m tall and it needs to hit a target that is 3.645 m away. What should the angle of the launcher be set to in order to hit the target?
*Marble is launched at a height of 1.17 m.
What I don't understand:
How can I solve this without the velocity? Am I suppose to find the velocity? And how do I find it?
After I do find the velocity, how am do I find time? Do I plug the info into this equation: d=vit + 0.5at2 to find the time? Then I am completely lost because I don't know what to do to find the angle.
Please I need help. It is 12:30 AM and I have a graded lab on this tomorrow.
