Kinematics of a Particle Tangent-Normal components

  1. Jan 14, 2007 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations

    a = (v^2/p) en + (v*)et
    a- accel
    en- inward normal
    et- unit vector along tangent
    v*- tangential acceleration
    p- curvature
    3. The attempt at a solution

    FOr the first part I just need to find the velocity using the above equation. Since velocity is constant a =0. Therefore tangential accel (at) = 0.4g.
    Then just solve for v. Now they gave us the dimensions of the car, so I guess I can't treat the car as a just a particle. The TA just told us to subtract the curvature from the given dimensions,BUT why are we doing that? :confused:

    so curvature = 120m - 0.6

    I believe the adjustment is made because the center of gravity of the car is slightly above the road surface.
