Answer:
0.1308
Explanation:
To keep the rider from sliding down, then the friction force 
must at least be equal to gravity force 
where μ is the coefficient, N is the normal force acted by the rotating cylinder, m is the mass of a person and g = 9.81 m/s2 is the gravitational acceleration.
According to Newton's 3rd and 2nd laws, the normal force would be equal to the centripetal force 
, which is the product of centripetal acceleration 
and object mass m
Therefore
The centripetal acceleration is the ratio of velocity squared and the radius of rotation
Therefore
True if you actually did it. false if you didn't
Answer:
<h3>The answer is 3.81 kg</h3>
Explanation:
The mass of the dog can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>3.81 kg</h3>

Physical science is defined as the study of observable phenomena in the universe.<span>The main idea of physical science is known as the "scientific method". </span>
<span>This method states: </span>
<span>1. observe a "real" ( not imaginary ) phenomena. </span>
<span>2. make a hypothesis ( or theory / idea ) that EXPLAINS this phenomena. </span>
<span>3. conduct a real experiment to test this hypothesis. </span>
<span>4. confirm that the experiment validates the original hypothesis and if necessary amend the theory. </span>
<span>This method is responsible for virtually every scientific explanation of every kind. </span><span>It has worked so well that the very communication you are having with me is a result of the wonders of physical science. </span>
<span>Hope your question was answered :)</span>
