- This is a statement.
- Relevant Equations
- ##f=\mu_{k} N## ##F=ma##
The question is stated above.
I tried to solve it on my own and I obtained the following three questions:
$$\begin{cases}
a_{cloth}=\frac{F-\mu mg} M\\
\\
a_{glass}=\frac{\mu mg}m=\mu g
\end{cases}$$
Where small m is the mass of the glass and capital M is the mass of the cloth. However, the first equation does not appear in the solution given by my answer book. So I think I must have wrongly interpreted the question. I would like someone to explain the question to me. Many thanks.
P.S. The official answer is shown below:
