Hello kevinlightmanis (i.e. speed is length / time)So:
isisandisSo the expression is dimensionally incorrect.
Here's my solution.
Eliminating between the equationsandwe getRe-arrange as a quadratic in :
Now the values of that satisfy this quadratic must be real. So:
Divide by , which we may do since :
Thus the values of and are bounded by the curve
which, I think, is the correct answer. (Unless you can see where I've made a slip?)
