1. At a given instant, a collar C slides along a horizontal rod that is rotating counter clockwise with an angular speed $\omega = 10 rad/s$ and an angular deceleration $\alpha = 20 rad/s^2$ as shown. At a distance of 5 m from the axis of rotation, the collar has a velocity of 10 m/s and a deceleration of 4 m/s² relative to the rod. (1) Determine the absolute velocity and acceleration of the collar at the instant shown. (10 pt) (2) Determine the required torque at the rotation axis and the frictional force between the collar C and the horizontal rod at this instant. The mass of the collar is 1 kg and its moment of inertia can be ignorable. The mass of the horizontal rod is 5 kg and its length is 10 m. Ignore the mass and moment of inertia for the vertical rod. (10 pt) (3) Determine the required torque at the rotation axis at this instant, if the radius of gyration of the collar C is 0.1 m (that is, its moment of inertia is not ignorable) and the other conditions are the same with (2). (10 pt)
