2. Relevant equations

a = (v^2/p) en + (v*)et

a- accel

v-velocity

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?

so curvature = 120m - 0.6
