Let me try:
Normal force= 169.74N
Coefficient of kinetic friction= 0.577
Explanation
a. For a given inclined plane, normal friction is equal to the force perpendicular to the plane which is equal to
mgcos theta = 20×9.8× cos30 = 169.74N
b. The coefficient of kinetic friction for an inclined plane is given as
tan theta =tan 30 = 0.577
I could only tell you if i knew what the figure looked like
Answer:
Hi myself Shrushtee.
Explanation:
Artificial gravity is a must for any space station if humans are to live there for any extended length of time. Without artificial gravity, human growth is stunted and biological functions break down. An effective way to create artificial gravity is through the use of a rotating enclosed cylinder, as shown in the figure. Humans walk on the inside edge of the cylinder, which is sufficiently large (diameter of 2235 meters) that its curvature is not readably noticeable to the inhabitants. (The space station in the figure is not drawn to the scale of the human.) Once the space station is rotating at the necessary speed, how many minutes would it take the space station to make one revolution?
The distance traveled by the man in one revolution is simply the circumference of the space station, C = 2p R. From this result, you should be able to deduce the time it takes for the space station to sweep out a complete revolution.

Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
as we know that angular acceleration of the wheel is given as
now the radius of the wheel is given as
R = 3.21 cm
so the tangential acceleration is given as
Part b)
frequency of the wheel at maximum speed is given as
now we know that
now radial acceleration is given as
Part c)
total angular displacement of the point on rim is given as
here we know that
now angular displacement will be
now the distance moved by the point on the rim is given as
