1. The problem statement, all variables and given/known data After a bobsled race, the sled and riders have been partially slowed down up in an icy incline, but they need to be brought to a stop. This happens on a portion of track inclined at 30 degrees that has a coefficient of kinetic friction of 0.60. The sled enters the incline at 25.0 m/s. How far does it travel along the incline before stopping? 2. Relevant equations Ff=UFn Fn=mgcosO f=ma 3. The attempt at a solution I couldn't find a way of doing it, since the , mass isn't given, maybe i'm overlooking something?
