- Mechanical energy. Solve for v

- Relevant Equations
- 1/2mv^2 + mgh

Hi there,

I am doing a mechanical energy question. I think the solution is simple but I'm stuck on an algebra step.

This is the solution but I am really not sure how they have simplified down to Va.

For example I tried to factor out the m resulting in

1/2mv^2=m(1/2va^2+gh)

Then I cancel the m

1/2v^2= 1/2va^2+gh

From here I am not really sure what they did to arrive at the final answer
