[Open]The kinetic energy of the car of a rollercoaster is given by the formula [tex]$k =\frac{1}{2} m v ^{ 2 }$[/tex], where k is kinetic energy, [tex]$m$[/tex] is the mass of the car, and [tex]$v$[/tex] is the velocity of the car. Solving this formula for [tex]$v$[/tex], we get [tex]$v=\sqrt{\frac{2 k}{m}}$[/tex]. Which formula gives the velocity of the car in simplest form? [tex]$v=\frac{\sqrt{2 k m}}{2 m}$[/tex] [tex]$v=\frac{\sqrt{2 k m}}{m}$[/tex] [tex]$v=\frac{\sqrt{2 k}}{m}$[/tex]
