Bobsled on a track

  1. A bobsled run leads down a hill as sketched in the figure above. Between points A and D, friction is negligible. Between points D and E at the end of the run, the coefficient of kinetic friction is µk = 0.4. The mass of the bobsled with drivers is 210 kg and it starts from rest at point A.

    I have no idea on this one. Could someone help me with the equations please!

  4. Sorry.
    Find the distance x beyond point D at which the bobsled will come to a halt.
