Similar to the last problem except that we don't initially know the angle of the velocity and acceleration so we can't take advantage of it.

Just finished the video series for dynamics, this was awesome! Super helpful for my midterm coming up, Thank you!

The problem question says the rod is "horizontal". This makes me think the rod is laid flat on the ground, meaning gravity wouldn't contribute to the equations.

When you are doing sum of the force in Θ direction (14:55), why did you multiply a Θ with 2?

I got the answers but they were switched. I assumed right side to be positive for transverse direction
