Question

Consider two blocks, of mass $m_1$ and $m_2$, being pushed across a floor as shown in the diagram. There is no friction between block $m_1$ and the floor, but the coefficient of static friction between $m_1$ and $m_2$ is $mu_s$. You are applying a constant force of magnitude $|vec{F}|$ horizontally, as shown. Block $m_2$ does not touch the floor: it is only in contact with $m_1$, but it does not slip relative to $m_1$. A. What is the acceleration of both blocks, $m_1$ and $m_2$? B. Find the smallest value of $|vec{F}|$ for which block $m_2$ will not slip relative to $m_1$. Both answers should only make use of given quantities ($m_1$, $m_2$, $mu_s$, $|vec{F}|$) and physical constants.

There is no friction between block $m_1$ and the floor, but the coefficient of static friction between
$m_1$ and $m_2$ is $mu_s$. You are applying a constant force of magnitude $|vec{F}|$ horizontally, as shown.
Block $m_2$ does not touch the floor: it is only in contact with $m_1$, but it does not slip relative
to $m_1$.
A. What is the acceleration of both blocks, $m_1$ and $m_2$?
B. Find the smallest value of $|vec{F}|$ for which block $m_2$ will not slip relative to $m_1$.

Consider two blocks, of mass m1 and m2, being pushed across a floor as shown in the diagram.
There is no friction between block m1 and the floor, but the coefficient of static friction between
m1 and m2 is mus. You are applying a constant force of magnitude |vecF| horizontally, as shown.
Block m2 does not touch the floor: it is only in contact with m1, but it does not slip relative
to m1.
A. What is the acceleration of both blocks, m1 and m2?
B. Find the smallest value of |vecF| for which block m2 will not slip relative to m1.
Both answers should only make use of given quantities (m1, m2, mus, |vecF|) and physical constants.
