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.
Find the distance x beyond point D at which the bobsled will come to a halt.
(delta)x = ½ v_o2/ mg
The Attempt at a Solution
I thought the bottom equation should be the right approach but I don't know how to find the velocity given the coefficient of kinetic friction and mass of the sled
