a 160g hockey puck slides horizontally along the ice, and the coefficient of kinetic friction between puck and ice is 0.15. if the puck starts sliding at 3 m/s before it comes to a stop it travels 3.6m how do you get to this answer?

    a 160 g hockey puck slides horizontally along the ice, and the coefficient of kinetic friction between puck and ice is 0.15. if the puck a tarts sliding at 3 m/s, how far will it travel before it comes to a stop?

  • physics -

    normal force = weight = .160*9.8
    friction force = -.15*.160*9.8
    a = F/m = -.15*.160*9.8/.160
    =-.15*9.8 =-1.47
    0 = vi + at = 3 - 1.47 t
    so
    t to stop = 3/1.47 = 2.04 seconds to stop
    d = vi t - .5*1.47 t^2
    =3*2.04 - .735*2.04^2
    = 6.02-3.06
    = 3 meters
