While working on an energy problem, you come up with a few different equations for the speed of an object at the bottom of a hill.

The variables stand for the following quantities.

$v$ : speed

g: acceleration due to gravity

$$ : coefficient of friction

$L$ : distance traveled

$h$ : height

Which one of these can be eliminated on the basis of a units check?

Select one from the below options:

The equation $v=\sqrt[\phantom{2}]{g(19L-2h)}$ can be eliminated because it doesn't pass a units check.

The equation $v=g\sqrt[\phantom{2}]{(19L-2h)}$ can be eliminated because it doesn't pass a units check.
