Newtons third law: If object A exerts a force on object B, the object B
exerts a force on object A, of the same magnitude but opposite direction.

Bobsled. A 170 kg boblsed must reach a speed of 10 m/s during the
allowed 50 m push-off stretch in order to be competitive. The
friction force is about 90 N, and well neglect drag in this example.

A 5.0 kg block rests on a table. The coefficient of static friction between
the block and the table is 0.60. If you push on it with a 20 N horizontal
force and it doesnt budge, how much is the static frictional force on the
