4) Consider a car traveling with speed  around a curve of radius r . a) Derive an equation that best expresses the angle () at which a road should be banked so that no friction is required. b) If the speed signpost says 42 mile/h, and the angle of the bank is 18°, what is the radius (r) of the curve. (2 points)

You must show how tan is derived mathematically.

A car is traveling around a banked curve without friction which is banked at 28 degrees. It is originally moving at 14 m/s. A constant acceleration of 2.5 m/s2 in the direction is applied in the direction that it is moving which causes the car to speed up. If this acceleration is applied for 2.7 seconds, how far did the car move up the road (the incline) in meters?
