A civil engineer is asked to design a curvedsection of roadway that meets the followingconditions:With ice on the road, when the coefficient ofstatic friction between the road and rubber is0.13, a car at rest must not slide into the ditchand a car traveling less than 70 km/h mustnot skid to the outside of the curve. The acceleration of gravity is 9.81 m/s2 .At what angle should the road be banked?Answer in units of degrees. Got this part already 7.4069What is the minimum radius of curvature ofthe curve?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
