Problem P. 4520. (March 2013)
P. 4520. The bodies arranged as shown in the figure are at rest; m_{1}=1 kg, =30^{o}. The rope attached to the body of mass m_{1} is horizontal.
a) Determine the magnitude of m_{2}.
b) Suppose that the rope which fixes the body of mass m_{1} brakes. What is the acceleration of the bodies when they begin to move?

Megoldásvázlat. \(\displaystyle a)\) \(\displaystyle m_2=2m_1=2\) kg.
\(\displaystyle b)\) \(\displaystyle a_1=\sqrt{3}g\approx17~\rm m/s^2\); \(\displaystyle a_2=0.\)
