Question

In the figure, block 1 of mass m1 = 1.8 kg and block 2 of mass m2 = 1.4 kg are connected by a string of negligible mass. Block 2 is pushed by force Upper F Overscript right-arrow EndScripts of magnitude 18 N and angle θ = 34°. The coefficient of kinetic friction between each block and the horizontal surface is 0.16. What is the tension in the string?

Answer 3

here is the situation of your problem:

the equation of the motion of both objects, are:
\[\Large \left\{ \begin{gathered}
{\mathbf{F}} + {\mathbf{T}} + {{\mathbf{R}}_2} = {m_2}{\mathbf{a}} \hfill \\
{{\mathbf{R}}_1} + \left( { - {\mathbf{T}}} \right) = {m_1}{\mathbf{a}}\quad \hfill \\
\end{gathered} \right.\]
