Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

**Computation:**

Three objects are connected as in the figure with \( m_A = 7 \) kg, \( m_B = 6.43 \) kg, and \( m_C = 11.4 \) kg. The strings and frictionless pulleys have negligible masses, and the coefficients of friction between the block and the table are \( \mu_s = 0.67 \) and \( \mu_k = 0.151 \). If the system is released from rest, find the magnitude of its acceleration.

[Hint: As part of your solution, check to see if block \( B \) experiences static or kinetic friction.]

\[
a = \, _____\, m/s^2
\]

Record your numerical answer below, assuming three significant figures.

**Diagram Explanation:**

The diagram displays a table with three masses connected by strings. Mass \( m_B \) is on the table; mass \( m_A \) is hanging on the left side, and mass \( m_C \) is hanging on the right side, both connected by strings that run over frictionless pulleys. The setup demonstrates the forces acting on the masses and how they are meant to influence each other's motion through the pulleys and strings.

A stone has a mass of 8.79 g and is wedged into the tread of an automobile tire, as the drawing shows. The coefficient of static friction between the stone and each side of the tread channel is 0.818. When the tire surface is rotating at 10.9m/s, the stone flies out the tread. The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 2.46 N. Assume that only static friction supplies the centripetal force, and determines the radius r of the tire (in terms of m)
