1.The 2-Mg truck is traveling at 15 m/s when the brakes
on all its wheels are applied, causing it to skid for a distance of
10 m before coming to rest. Determine the constant horizontal
force developed in the coupling C, and the frictional force
developed between the tires of the truck and the road during
this time. The total mass of the boat and trailer is 1 Mg.
v0 = 15 m/s
s = 10 m
Fk = µkN
2. I'm not exactly sure how/where to start. I also have no idea how to get the frictional force.
I figure that since I know v0 and vf as well as s0 and sf that I can get deceleration.
I'll use v2 = v02 + 2a(s-s0). If I solve for a, maybe that will help get the frictional force?
