A truck used to demolish a building obstructing the construction of a bridge. This truck contains a wrecking ball of weight (60 kg). This ball is connected to a (15-meter) long steel cable and moves in a vertical arc as shown in the figure. If you know that ball velocity when it reaches (point B) is (4.2 m/s). What is the tensile force of the cable in case: (a) The ball reaches its maximum swing (at point C). (b) When the ball reaches the bottom of the swing (at point D). Geod dueh! 20

Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
