QUESTION:

Three cars are driving at 25 m/ s along the road shown in FIGURE P8.41. Car B is at the bottom of a hill and car C is at the top. Both hills have a 200 m radius of curvature. Suppose each car suddenly brakes hard and starts to skid. What is the tangential acceleration (i.e., the acceleration parallel to the road) of each car? Assume \(\mu_{\mathrm{k}}=1.0\).

Equation Transcription:

${\mu{}}_{k}\ =\ 1.0$

Text Transcription:

mu_k = 1.0
