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.
