Should I only be concerned with the forces of the car when it is stopped? If so, would it be F = mgsin(5)? Then I get: mgsin(5) = μmgcos(5) which would give me: μ = tan(5) = .0875, but that seems too small.

Homework Statement A 1980kg car starts from rest at point A on a 5° incline and coasts through a distance of 158m to point B. The brakes are then applied, causing the car to come to a stop at point C, 21m from point B. Knowing that slipping is impending during the braking period and neglecting...

A 4000kg freight car rolls along rails with negligible friction. The car is brought to rest by a combination of two coiled springs as illustrated in the figure below. Both springs are described by Hooke's law with k1 = 1700N/m and k2 = 3500 N/m. After the first spring compresses a distance of...
