Homework Help: Physics

Posted by Cody on Saturday, September 29, 2012 at 12:59am.

A 1500 kg car moves along a horizontal road
at speed v0 = 21.9 m/s. The road is wet,
so the static friction coefficient between the
tires and the road is only Ás = 0.302 and
the kinetic friction coefficient is even lower,
Ák = 0.2114.
The acceleration of gravity is 9.8 m/s^2

Assume: No aerodynamic forces; g =
9.8 m/s^2

Forward is the positive direction.
What is the highest possible deceleration of
the car under such conditions?
Answer in units of m/s^2
