Question

Solve for u. m/u^2+r=−k−y

Answer 1

Answer: +/- sqrt(m/-k-y-r)

Explanation:

Answer 2

9514 1404 393

Answer:

u = ±√(-m/(k+r+y))

Explanation:

Subtract r, rearrange, then take the square root.

`(m)/(u^2)+r=-k-y \qquad\text{given}\\\\ (m)/(u^2)=-k-y-r\\\\-(m)/(k+r+y)=u^2\\\\ \boxed{u=\pm\sqrt{-(m)/(k+r+y)}}`
