You need two points to calculate it. The slope is then the coefficient of the line passing for the two points, i.e.: m = ( y2 - y1 ) / ( x2 - x1 ) To get it in form of an angle use the arctan(m) function.
Until now in physics, you've probably been ignoring friction to make things simpler. Now, it's time to include this very real force and see what happens. Feb 02, 2016 · (a) Calculate the acceleration of a skier heading down a 10.0o slope, assuming the coefficient of friction for waxed wood on wet snow. (b) Find the angle of the slope down which this skier could coast at a constant velocity. You can neglect air resistance in both parts. Static friction μs:0.14 Kinetic friction μk:0.1
Motion on a Curve => The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve. => For a level curve, the centripetal force will be supplied by the friction force between the tires and roadway.
