Sure. But it's nice to have options. Some approaches are more intuitively obvious to different people.

If you use energy, then you have to introduce mass and this is not necessary.

Mass disappears by cancellation. No biggie. Or use specific energy

It's no more complicated an approach if you're familiar with the concept. Like I said, different strokes for different folks.

Let's wait to see what the OP comes up with.

Note that this equation is assuming that acceleration, the derivative of velocity with respect to time, is constant. This is, then, just a simple exercise in calculus.## Homework Statement
