A 230-kg roller coaster reaches the top of the steepest hill with a speed of 5.20 km/h. It then descends the hill, which is at an angle of 25° and is 50.0 m long. What will its kinetic energy be when it reaches the bottom? Assume µk = 0.16

I'm not sure how to set up the problem and which equation to use.
