Answer:

[tex]u=(9-\frac{1}{2}at^{2})/t[/tex]

Step-by-step explanation:

we have

[tex]9=\frac{1}{2}at^{2}+ut[/tex]

Solve for u

That means-------> isolate the variable u

step 1

Subtract  [tex]\frac{1}{2}at^{2}[/tex] both sides

[tex]9-\frac{1}{2}at^{2}=ut[/tex]

step 2

Divide by  [tex]t[/tex] both sides

[tex]u=(9-\frac{1}{2}at^{2})/t[/tex]

Answer:

The formula for u is [tex]u=\frac{9-\frac{1}{2}at^2}{t}[/tex].

Step-by-step explanation:

The given equation is

[tex]9=\frac{1}{2}at^2+ut[/tex]

Step 1: Subtract [tex]\frac{1}{2}at^2[/tex] from both the sides.

[tex]9-\frac{1}{2}at^2=ut[/tex]

Step 2: Divide both sides by t.

[tex]\frac{9-\frac{1}{2}at^2}{t}=u[/tex]

Therefore the formula for u is [tex]u=\frac{9-\frac{1}{2}at^2}{t}[/tex].
