a 0.0215m diameter coin rolls up a 20 degree inclined plane. the coin starts with an initial angular speed of 55.2rad/s and roll
marissa [1.9K]

Answer:

h = 0.0362\,m

Explanation:

Given the absence of non-conservative force, the motion of the coin is modelled after the Principle of Energy Conservation solely.

U_{g,A} + K_{A} = U_{g,B} + K_{B}

U_{g,B} - U_{g,A} = K_{A} - K_{B}

m\cdot g \cdot h = \frac{1}{2}\cdot I \cdot \omega_{o}^{2}

The moment of inertia of the coin is:

I = \frac{1}{2}\cdot m \cdot r^{2}

After some algebraic handling, an expression for the maximum vertical height is derived:

m\cdot g \cdot h = \frac{1}{4}\cdot m \cdot r^{2}\cdot \omega_{o}^{2}

h = \frac{r^{2}\cdot \omega_{o}^{2}}{g}

h = \frac{(0.0108\,m)^{2}\cdot (55.2\,\frac{rad}{s} )^{2}}{9.807\,\frac{m}{s^{2}} }

h = 0.0362\,m

A 2.35-m-long wire having a mass of 0.100 kg is fixed at both ends. The tension in the wire is maintained at 22.0 N.
ahrayia [7]

Length of wire (L)=2.35m

Mass of wire (m)=0.100kg(m)=0.100kg

Tension in the wire (T)=0.042m

<h3>What is tension?</h3>

Any physical object that is in contact with another one can apply forces to that item. Depending on the sorts of objects in touch, we label these contact forces differently. We refer to the force as tension if a rope, string, chain, or cable is one of the things applying the force.

Ropes and cables can effectively convey a force over a long distance, making them valuable for exerting forces (e.g. the length of the rope). For instance, a team of Siberian Huskies can pull a sled by attaching ropes to them, allowing the dogs to move more freely than if they had to push against the sled's rear surface with their typical effort.

In which situation is no work being done?
Nataliya [291]
I would say that work is being done in all the situations because technically in physics work is done whenever force is applied through a distance.
