Bobsled physics problem

  1. Jan 28, 2007 #1
    1. The problem statement, all variables and given/known data
    The coefficient of kinetic friction for a 26-kg bobsled on a track is 0.13. What force is required to push it down a 4.1° incline
    and achieve a speed of 7.0E1.0 km/h at the end of 73 m?

    2. Relevant equations
    Force friction=F*k

    And just sum of forces=0

    3. The attempt at a solution
    I'm lost...

    So this is two problems rolled up into one. On one hand you need to figure out what acceleration will let you reach a speed of 70 km/h after traveling 73 m, and then you will also need to figure out what force when summed against the frictional force will provide that acceleration.
