A mass (between 0.01 kg and 1 kg) is hung by a string from the edge of a massive (between 0 kg and 2 kg) disk-shaped pulley (with a radius between 0.1 and 4 meters) as shown (position given in meters, time given in seconds, and angular velocity given in radians/second). Time: 1,48 omega = +7.252

please answer quickly! Will rate!  49

The rotating systems shown in the figure differ only in that the two identical movable masses are positioned a distance r from the axis of rotation (left), or a distance r/2 from the axis of rotation (right). If you release the hanging blocks simultaneously from rest, O A. the block at the right lands first. O B. both blocks land at the same time. O C. the block to the left lands first.

Because 2? rad = 1 rev, the angular displacement in part (b) corresponds to 2.23 rev. In general, dividing the number of radians by 6 gives a good approximation to the number of revolutions, because 2? ~ 6.QUESTION If the angular acceleration were doubled for the same duration, by what factor would the angular displacement change?

Looking for guidance to question based on characteristics/assumptions of experiment: Experiment background: For our dynamic measurement of the moment of inertia, we will use a vertically-mounted turntable that has a hub attached at its center, which has three grooves of different radius, around which one can wind a string. A mass hanging from the free end of the string provides tension, which exerts a torque on the turntable, thus causing it to rotate. By measuring the time it takes the mass to fall from its initial height to the table top (or some reference line just above it), we can find aa, its (linear) acceleration. From this we can calculate αα, the angular acceleration of the turntable. From the weight of the mass, and its linear acceleration, we can find T, the tension in the string. Once we know all these things, we can calculate the torque, ττ, and from τ=Iατ=Iα find I, the moment of inertia of our turntable platter. Assumptions made in this experiment:  - Turntable disk…

Advanced Physics: The picture shows a view from above of a non-uniform object (a rectangular slab with objects placed on it) dropped onto a platform rotating on a low-friction bearing. The mass of the rotating disk is 2.85 kg. 1. Show a Force Diagram 1. Make measurements and calculations to determine the rotational inertia of the slab (including the objects on the slab). Explain your process and results below. 2. Describe the major assumptions you made during your process. 3. Do you think the actual value of the rotational inertia of the slab (with the objects on it) is more likely to be greater than your value, or less than your value? Support your assertion.
