    1. The problem statement, all variables and given/known data

    While sledding you reach the flat bottom of the hill while moving 8.0 m/s^2. The μ (kinetic) between the sled and snow is μk= .080. The mass of you and the sled is 95 kg. How long does it take to stop the sled?

    I'm not sure how to do this problem and ive been trying for a while. if i could please get some help i would greatly appreciate it!
