Hi all,
I'm stuck on a system of equations I am left with at the end of a dynamics problem.
[itex]
a=-b+v
[/itex]
[itex]
x=-b+vcos(30)
[/itex]
[itex]
y=vsin(30)
[/itex]
[itex]
171.5=20b^2+5a^2
[/itex]
[itex]
a^2=x^2+y^2
[/itex]
[itex]
10x-40b=0
[/itex]
All in degrees.
I know I have an extra equation, but I thought I'd include it in case it is easier to solve with a certain five of them. I know it's not as simple as solving for one variable in terms of one other, plugging in and solving. I tried looking at it for ways to recombine the equations- no luck.
Thank you,
Jack
