A skier of mass 67.5 kilogram is racing down a real hill with an angle of incline of 9.78 degrees. If the total resistive forces of friction (this includes air resistance and the friction between the skies and the snow) are 14.3 newtons, what is the acceleration of the skier in metres per second squared? Just give me the number.

    Question 1 1 pts A snow skier is racing directly downhill on snow with a kinetic friction coefficient (between the snow and the skis) of 0.05. The angle of the slope is 40 degrees. The mass of the skier and ski equipment is 78 kg, the skier's cross-sectional area (in a "tucked" position) is 1.4 m2, the drag coefficient with respect to the air is 0.14 and the air's density Pair =1.21 kg/m3. What is the skier's terminal speed going...

    university physics please show your work ..sliding down a grass hill on a piece of cardboard was a fun summer activity! There was a hill near a park in south St. Louis that had an incline of something like 30 degrees. Once I got started on the top of the hill, I could ride for a distance on the order of 50 meters before arrived at the bottom of the hill. At that time, my mass was just a puny...
