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.

Two cars on two hills on equal raduis of curvature

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.

Answer Section#

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.

Answer Section#

Please enter in a numeric value in \( m{ rac{m}{s^2}}\).
