Question
An object glides on a horizontal tabletop with a coefficient of kinetic friction of 0.55. If its initial velocity is 4.1 m/s, how long does it take for the object to come to rest?

F = m a
-.55 * m * g = m * a
a = -.55 g = -5.39
v = Vi + a t
0 = 4.1 -5.39 t
t = 4.1/5.39
-.55 * m * g = m * a
a = -.55 g = -5.39
v = Vi + a t
0 = 4.1 -5.39 t
t = 4.1/5.39
