A curve of radius 75 m is banked for a design speed of 90 km/h . If the coefficient of static friction is 0.31 (wet pavement), at what range of speeds can a car safely make the curve? [Hint: Consider the direction of the friction force when the car goes too slow or too fast.] Express your answers using two significant figures separated by a comma.

A train slows down as it rounds a sharp horizontal turn, going from 88.0 km/h to 56.0 km/h in the 13.0 s that it takes to round the bend. The radius of the curve is 160 m. Compute the acceleration (both magnitude and direction) at the moment the train speed reaches 56.0 km/h. [Assume the train continues to slow down at this time at the same rate.]
