Inclined plane Definition and 822 Threads

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...

i think this is an easy question but i forgot how and the book doesn't want to tell me. can anyone tell me how to figure this out? thanks. A soccer ball is released from the top of a smooth incline. After 4.58 s the ball travels 10.8 m. One second later it has reached the bottom of the...

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?

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...

The formula for calculating the force required to move an object (ignoring friction, etc.) up an inclined plane is: F = Mgsinθ Where: F = force (N) Mg = gravity (9.81m/s²) θ = angle of inclination (degrees out of 360, or radians?) The question I have is: what is used to...
