a 0.0818 kg salt shaker on a rotating table feels an inward frictional force of 0.108 N when it is moving 0.333m/s. what is the
serg [7]

<u>Answer:</u>

<em>The required radius of its motion is 0.084m.</em>

<u>Explanation:</u>

The formula for calculating the required  radius of its motion is given by

F = (mv^2)/r

Where <em>m= mass  </em>

<em>V= moving velocity </em>

<em>F=frictional force </em>

<em>r = radius of its motion </em>

Then the required radius of its motion is given by

r =(mv^2)/F

<u>Given that </u>

<em>mas =0.0818 kg </em>

<em>Frictional force= 0.108 N </em>

<em>Moving with Velocity of  = 0.333 m/s </em>

<em>radius of its motion = \frac{[0.0818 kg \times (0.333 m/s)^2]}{0.108 N}</em>

<em>Hence the required radius of its motion is r = 8.4 cm=0.084m</em>

A solid uniform sphere of mass 5 kg and radius 0.1 m rolls down an inclined plane without slipping. if the sphere's center of ma
ANTONII [103]

Since sphere is performing pure rolling motion

So here the contact point of sphere with respect to inclined plane is always at rest.

This contact point will not move at any instant and and hence sphere will perform pure rolling.

So here we can say that sphere will have some friction force at the contact point but there is no displacement of that point.

So the work done by this static friction will always ZERO.

W_{friction} = F.d

W_{friction} = 0

So there is no work done by friction on the sphere while it is in pure rolling.

A 10kg ball has a momentum of 40 kg.m/s. What is the ball’s speed.
Whitepunk [10]

Answer:

<h2>4 m/s</h2>

Explanation:

The speed of the ball can be found by using the formula

s=  \frac{p}{m}  \\

p is the momentum

m is the mass

From the question we have

v =  \frac{40}{10}  = 4 \\

We have the final answer as

<h3>4 m/s</h3>

Hope this helps you
