In the first part of this lab, you will find the coefficient of static friction between paper and a book so we want the surface of the ramp to be paper. This can be done either by making your ramp out of paper (by using a notebook) or by taping a piece of paper to the surface of a ramp.
Conduct your experiment. You should perform at least three trials. Create a data table that includes all of the data taken in your experiment and the coefficient of static friction found from each trial. Find the average value of the coefficient of static friction between the paper and your book.
What type of data do I need to record when performing this experiment?

Expert Solution
The following things you should note:
1) initial velocity (v)
2) the distance travelled before it stops (s)
I have explained both, a way to find the coefficient of kinetic friction, and a way to find the coefficient of static friction.

The coefficient of friction (static and kinetic) between an
object and a surface can be measured by putting the object on an
adjustable inclined plane. (a) Draw a free-body diagram for the
object, assuming static friction holds it in place on the incline.
(b) Find an equation that can be used to solve for µs, in terms of
the angle θmax which is the largest angle that the object can sit
without sliding. (Hint: You can reduce the problem to...

#4. A vase was placed on the coffee table. The
coefficient of static friction between the vase and the table is
0.3689, whereas the coefficient of kinetic friction is 0.1339. The
vase weighs 1.0707kg. A cat decided to redecorate the room by
pushing the vase off the table. As the cat pushes the vase with its
paw, the vase moves. Then, the cat maintains a constant applied
force of 7.37N on the vase in the positive x-direction. What is the...

A mass of 8 kg rests on a floor with a coefficient of static
friction of 0.88 and coefficient kinetic friction of 0.33. One
force is applied vertically downward of 28 Newtons and another
force is applied at an angle of 26 degrees below the horizontal.
Calculate what the magnitude this force needs to be in order to
begin to move the mass. If that force is removed and another force
is applied at an angle of 26 degrees above...

A mass of 6 kg is placed on an incline with a coefficient of
static friction of 1.80 and coefficient of kinetic friction of
1.28. No additional forces are acting on it and it is raised slowly
from a small angle and it begins to slide at some angle. If 10
degrees is added to this angle, and the mass started from rest from
a vertical height of 28 meters, how much longer would it take to
travel down the...

If the coefficient of static friction is 0.60, and the same
ladder makes a 46° angle with respect to the horizontal, how far
along the length of the ladder can a 55.0-kg person climb before
the ladder begins to slip? The ladder is 7.5 m in length and has a
mass of 21 kg.

Remarks It's interesting that the final result
depends only on the coefficient of static friction. Notice also how
similar Equations (1) and (2) are to the equations developed in
previous problems. Recognizing such patterns is key to solving
problems successfully.
