Hi there! Thank you for the opportunity to help you with your question!

I assume the equation is:

In that case, what you are asked to do, is to manipulate the equation algebraically, so that you isolate vf.

This would involve multiplying both sides by 2, then dividing both sides by t, and finally, subtracting vt. The final answer would be:

so the final answer is

2s/t - vt

Does that make sense?



Please let me know if you need any clarification. Always glad to help!
