You have to write your expression clearly. What is "(33 - T over 22......
Do you mean (33 - T)/22 or 33 - (T/22)?. In any case you just have to plug numbers into the formula and calculate W. What I can't understand in your expression is coexistence of two terms with different units:
sqrt (v) and v. In this case the coefficient 10 must have an appropriate units to make the product
10sqrt(v) having the same units with "v" (m/sec). Please make this clear.
