Newton's Second Law Prelab Assignment
Name:_______________________________
4-digit Code Number:_______________________________
- Consider the following Atwood's machine with
m2 > m1,
and with a massless, frictionless ideal pulley.
- What is the acceleration of the mass m2?
- What is the tension in the string?
- Mass m1 rests on a rough horizontal surface while mass
m2 hangs over a massless, frictionless ideal pulley.
Explain in detail how this setup could be used to determine
the coeficient of static friction
s
between m1 and the table.
(Remember, this is static friction, so what is the
acceleration?) That is, explain carefully
- what quantities must be measured,
- with what instruments quantities are to be measured (only measuring
instruments that you have used previously in this course),
- what procedures are to be used, in particular how the maximum value
of m2 is determined,
- and derive an equation for
s
in terms of the quantities above.
