Question

Consider a system composed of three masses connected by light rigid rods. The first mass (\(m_1 = 3.00\) kg) is positioned 2.75 meters along the y-axis. The second mass (\(m_2 = 4.00\) kg) is situated 2.50 meters along the x-axis. The third mass (\(m_3 = 2.50\) kg) is located at the coordinates (-4.00, -3.30) meters. This third mass is connected to the first and second masses such that the system's center of mass is at the origin.

The entire system rotates around the origin. A constant force with a magnitude of 2.9 N is applied to the left on \(m_1\), and a force of 9.7 N is applied downwards on \(m_2\).

What is the resultant angular acceleration of the system about the origin, considering positive angular acceleration out of the page?

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
