I have no trouble doing a calculation for the angular acceleration of the "big disc" with the 2.5 kg rope hanging off the side, and a calculation for the angular acceleration of the "small disc" with the 4.0 kg mass hanging off the side. But I just can't seem to understand the connection of how...

So am I understanding your explanation correctly by submitting the following? (b) velocity with respect to the road = velocity of CM + velocity of the dot with respect to the CM velocity with respect to the road = 5.6 m/s + 5.6 m/s velocity with respect to the road = 11.2 m/s (c)...

But when it is 0.8 m above the road, and hence, the full diameter of the wheel, is the speed not tangentially in the same direction as the road, and therefore 5.6 m/s? (It isn't, I know this answer is wrong but am not sure why). Is it because it will have the cumulative linear speed of the...

Homework Statement A bicycle with 0.8 m diameter tires is coasting on a level road at 5.6 m/s. A small dot has been painted on the rear tire. What is: a) the angular speed of the tire b) the speed of the dot when it is 0.8 m above the road in m/s? c) the speed of the dot when it is 0.4 m...

I am a high school teacher tutoring a family member in an introductory university class. I have good knowledge of typical pulley questions and semi-decent knowledge of angular acceleration (it is no longer in the high school curriculum here and I am out of practice). Can anyone give me a...
