Homework Help: Inclined plane problem with friction

  1. Oct 16, 2016 #1
    1. The problem statement, all variables and given/known data
    During a flume ride the boat plunges 54 feet down a 43 degree incline. Assuming coefficient of friction .12 determine the acceleration of the boat.

    2. Relevant equations
    I'm really not sure, no mass is given or force. All of the equation I know involve mass or force.

    3. The attempt at a solution
    Im not even sure how to find horizontal or vertical components without mass. Acceleration due to gravity is 9.8 m/s^2. Used tangent to find the sides of the triangle. So I'm stuck, no idea where to even start. Really appreciate any suggestions.

    Apply your usual formulas with mass included, leaving the mass as a variable. You should find that it cancels out along the way (so you didn't really need it after all).
