Question

can you please show me how to solve for v?
8=1/2at^2+vt

Answer 1

This is a quadratic equation where t is the variable.

Move everything to one side of the equal sign and use the quadratic equation.

\(\frac{1}{2}at^2 + vt - 8 =0 \)

Answer 2

subtract off the 1/2at^2 from each side then divide off the t to get v all by its little lonesome

Answer 3

later on in physics you might come across this equation, but for now ...

Answer 4

\[½at ^{2}+vt−8=0\]
\[vt−8=-½at ^{2}\]
\[vt=-½at ^{2} +8\]
\[v=[-½at ^{2} +8]/t\]
