A box with mass m is on a frictionless inclined ramp. The ramp has an angle of with respect to the horizontal. The ramp is firmly attached to the inside of a car. The car is traveling to the right, and is slowing down. The car has a constant acceleration with magnitude a. You observe that while the car is slowing down, the box doesn't slide up or down the ramp. a) What is the angle of the ramp? the answer should be in variables, using only m, g, and a. This problem should be solved using the "recipe" taught in class. The "recipe" has four steps. To be graded correct, you must clearly show all four steps! b) Suppose that the driver now presses harder on the brakes. Would the box slide up the ramp, or slide down the ramp? Or would it not slide at all?
