The Sliding Block with friction

Now let's look at that ramp again ....

A box of mass M=10 kg sits on a ramp of angle theta=20 degrees. The coefficient of static friction between box and ramp is 0.30, and the coefficient of kinetic friction is 0.20.

  1. Draw a set of coordinate axes which are tilted to match the ramp, so that the x-axis goes parallel to the slope and the y-axis goes perpendicular to it.
  2. What is the normal force between the box and the ramp?
  3. What is the magnitude of the force pulling the box down along the surface of the ramp?
  4. What is the maximum possible force of friction on the box?
  5. If you hold the box at the top of the ramp, then release it, does it slide downwards?
  6. If not, how much must you increase the tilt of the ramp in order to make the box start to slide?
  7. The ramp is tilted at theta=60 degrees. How fast does the box accelerate down the ramp?
