In nascar, the race cars move through banked turns. if a car with mass m is traveling in a circle on a road that has an incline of theta with respect to the horizontal like these banked turns and the radius of the circle is the speed of the car is and the coefficient of static friction is , derive the expressions for the maximum and minimum angles that the incline can be without the car sliding up or down in terms of, and you must define the x-axis to be along the slope and the y-axis to be perpendicular to the slope as well as showing your work.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
