0 kg mass slides on a horizontal surface with a coefficient of kinetic friction of 0. The mass is initially moving at 4.0 m/s. Use g = 10 m/s2.

A 5.0 kg mass slides on a horizontal surface with a coefficient of kinetic friction of 0.2. The mass is initially moving at 4.0 m/s. Use g = 10 m/s2.

What is the magnitude of the kinetic friction force on the mass?

How far does the mass slide before coming to rest?
