Two curves on a highway have the same radii. However, one is unbanked and the other is banked at an angle ɵ. A car can safely travel along the unbanked curve at a maximum speed v under conditions when the coefficient of static friction between the tires and the road is μs = 0.787. The banked curve is frictionless, and the car can negotiate it at the same maximum speed v. Find the angle ɵ of the banked curve.

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
