If this were to happen then the particle would be at the node (the point in the middle where the lines meet). Therefore, the particle will not move up or down because you can see the waves interfere destructively so there is no movement at the node.
answer. The particle will remain stationary due to interference.
the answer is c) when it becomes excessive, uncontrollable , and affect daily life
Explanation:
Below is an attachment containing the solution.
Answer:
w=3.05 rad/s or 29.88rpm
Explanation:
k = coefficient of friction = 0.3900
R = radius of the cylinder = 2.7m
V = linear speed of rotation of the cylinder
w = angular speed = V/R or to rewrite V = w*R
N = normal force to cylinder
N=
These must be balanced (the net force on the people will be 0) so set them equal to each other.
There are 2*pi radians in 1 revolution so:
So you need about 30 RPM to keep people from falling out the bottom
