Question: James and Steve have a contest to see who can kick a football further. James kicks the football at an angle up of 57 degrees, and a speed of 75m/s. Steve kicks the ball with a speed of 100m/s, at an angle up of 48 degrees? Who wins the contest?
First, I don't really understand what variables I have and don't have. I know you can find Vix but doing 75cos57 and viy by doing 75sin57. I think I have to find time but like I said I am don't understand what variables I have or what variables I need.
Secondly, is this a two part questions? The fact that there are two different people is really confusing me.
The Attempt at a Solution
okay here is my small attempt. I assumed that vfy=0 and vfx=0 (this doesn't seem right but I tried it anyway). Then I pulled what variables I think I had into this equation: vfx=vix+axt
With the number it looked like this 0=40.8-9.81(t)
After this I just didn't know what to do.
What I need help with: I need help clarifying the variables and knowing what variables I need
Knowing what equation to use
