If you mean points of: (-10, 5) and (100, 5.7) then the slope works out as 7/1100
the normal force is acting on the sled-- it's what keeps the sled from falling through the slope
To convert 'D' degrees into a percent slope, you could use the Excel formula:= 100 * TAN ( D / 57.296 )
The angle of depression is equal to the angle of elevation, so use the sine ratio to find the angle. sine = opposite (the vertical drop) divided by the hypotenuse (the ski slope) sine = 100/250 = 2/5 or 0.4 sine-1(0.4) = 23.57817848 degrees which is about 24 degrees
|32 - 132| = |-100| = 100 |32 - 132| = |-100| = 100
