    Inclined plane car out of gas problem

    A car traveling at 25.0m/s runs out of gas while traveling up a 22.0 degree slope. How far up the hill will it coast before starting to roll back down? i tried doing (2*25m/s)^2 / cos22*-9.8cos68 but that wasn't the right answer... ~help please?

    Forces on an Inclined Plane Question

    Hi I have a problem that reads: A car drives downhill on a road that is inclined 20 degrees to the horizontal. At a speed on 30 m/s the driver suddenly brakes until the car stops (coefficent of kinetic friction = .8, coefficent of static friction = .9). A. When all of the wheels are locked...

    Block on Inclined Plane: The Effects of a Fixed vs. Unfixed Surface

    Hi, I recently did a problem in which a block of definite mass was placed on the top of a inclined plane which was inclined at some angle with the horizontal. The block starts to slide down. What would happen if the inclined plane was not fixed?

    Flow of a Newtonian fluid down an inclined plane.

    I'm basically reading on how the velocity profile is found for a laminar flow of a Newtonian fluid down an inclined plane surface. (x is along the incline, y is perpendicular to the incline) The assumptions being made are - The fluid is Newtonian - It's laminar - It's fully developed - It's...

    Normal force on inclined planes.

    If a car is going up or down an inclined plane, the normal force on the car is just mg cos (theta). However, if a car is turning on an inclined curve, the normal force is mg/cos(theta). Why are the two normal forces not the same? To clarify, here is an example problem: A highway curve...
