# Cars on Hills#

Two cars are driving at 23 $$\rm{m/s}$$ along the road shown in the figure. Car B is at the bottom of a hill and car C is at the top. Both hills have a 154 $$\rm{m}$$ radius of curvature. Suppose both cars suddenly brake hard and start to skid.

## Part 1#

What is the tangential (parallel to the road) acceleration of car B? Assume $$\mu_k = 0.850$$ and car B has velocity in the positive direction.

Please enter in a numeric value in $$m{ rac{m}{s^2}}$$.

## Part 2#

What is the tangential (parallel to the road) acceleration of car C? Assume $$\mu_k = 0.850$$ and car C has velocity in the positive direction.

Please enter in a numeric value in $$m{ rac{m}{s^2}}$$.
