I have the same question, with different numbers. I do not understand which formula I am to use that relates the force applied to both the translational and rotational dynamics. I realize that the tangential acceleration and centre of mass acceleration are the same.
If I say that Fext=ma and...
Homework Statement
A Ferris wheel with a radius of 9.7m rotates at a constant rate, completing one revolution every 39s.
Suppose the Ferris wheel begins to decelerate at the rate of 0.19rad/s^2 when the passenger is at the top of the wheel.
Find the magnitude of the passenger's...
I wish my lectures will all recorded and online, however some of my teachers don't allow it as they want students to come to class. I would imagine my brand new 500 person lecture theatres for Chemistry and Physics would be quite empty if it was all online, and the class average would drop too...

Force of tension externally is 150N [up]
Acceleration is 2.99 m/s^2 [down]
Mass A is the highest and is 4kg
Mass B is attached to Mass A by a light (negligible) string, Mass B is 6 kg

I go to all my lectures mainly for two reasons:
A) lack of self motivation to study the material, I'd rather go to those and party on the weekends
B) I find I am very good at getting a feel from the professor as to what they will put on examinations by the amount of time they spend on it, and...
Ah yes it is a system of equations... I always over think those. Thank you very much!
And yes I did you d for displacement, however you are more correct as d would represent distance, not displacement.
1. I have been given the total distance (100m) and the total time (9.780s) as well as a speed (11.7m/s) at t1 and a final speed (10.5m/s) at the end of the given time (9.780s). The initial velocity is zero at t=0. Acceleration is constant. I am not asking for the answer, just an algebra based...
