a skater with an initial speed of 7.60m/s is gliding across the ice. air resistance is negligible. (a)the coefficient of kinetic friction between the ice and the skate blades is 0.100. find the deceleration caused by kinetic friction. (b)how far will the skater travel before coming to rest?

can anyone please give me some hints to do it? THANKS A LOT!

  1. If the kinetic friction coeffient is 0.1, the force that is opposig motion is (F = 0.1 * M g).

    (a) The deceleration rate is therefore
    a = F/M = 0.1 g = 0.98 m/s^2

    (b) The time to come to rest, T, is given by
    a T = 7.6 m/s.
    Solve for T

  2. i don't understand how you get this part..a = F/M = 0.1 g = 0.98 m/s^2
