• You are on top of a snowy mountain on a snowboard. You need a little push by your friend in order to start sliding.

The coefficient of static friction between the snow and the snowboard is 0.1 and assume your normal force is 800N.

Find the net force if your friend was to push you to the right with a force of 80N.

A 200 kg snowboarder starts from rest down a slope inclined at 20 degrees from horizontal. If the coefficient of friction between the snowboarder and the slope is 0.13, what is the resulting acceleration of the skier down the slope? If the slope is 200 m long and the skier continues to accelerate, how fast will the skier be going at the bottom?

A 75- snowboarder has an initial velocity of 5.0 at the top of a 28 incline. After sliding down the 110- long incline (on which the coefficient of kinetic friction is = 0.18), the snowboarder has attained a velocity . The snowboarder then slides along a flat surface (on which = 0.15) and comes to rest after a distance .
