The length of the incline (not vertical height of hill, but hypotenuse (sp?) of hill triangle) is 19.7 m.

The height of the hill is around 7.5 meters.

Note: 1 pound = 4.45 Newtons

You can use your weight in pounds to find your weight in Newtons. Then you can calculate your mass. You could probably add around 3 kgs for your coat, boots, snow pants, & sled.
