Doug hits a record hockey, giving an initial speed of 6.0m / s. If the coefficient of kinetic friction between ice and the disc is 0.050, how far it slides the disk before stopping? I help to show the work please, I understand and thanks
F = ma friction μ = ur-(mg) = MA – (0,050) (m) (9.8) = ma a = – 0.49 m / s ² v ² = 2a + u ² 0 ² = 2 (-0.49) (s) + (6) ² = 36.73469388 m s
