DISCUSSION and HINTS

Recall the following four-step plan outline in the lecture book and discussed in lecture:

Step 1: FBDs
Draw a free body diagram (FBD) of the disk.

Step 2: Kinetics (Newton/Euler)
Based on your FBD above, write down the linear impulse momentum and angular impulse/momentum equations for the disk.

Step 3: Kinematics
What kinematics do you need here to solve?

Step 4: Solve
From your equations in Steps 2 and 3, solve for angular velocity of the disk at time 2 and the reactions at O.
