Gravity will accelerate your marble down the ramp. Your ramp is at an incline though, and you thus need the Y$-$component of this acceleration since gravity acts in the Y direction. Replace the acceleration variable in Question $6$b with that component, which is $9\mathrm{.}81*$sin$($$)$ m$/$s$2,$ where is the angle of the ramp. Record your answer in

variable form.

You should now have an equation that includes the square of the final velocity as a function of acceleration and distance. Solve this equation by taking the square root and state it below it in variable form.
