In principle, no impact. However your arms are not straightforward pendulums, on the grounds that they have mass, grating, and the length changes as indicated by the weight conveyed Hence when all is said in done, the heavier the weights the lower your arms will swing. I trust the appropriate response will help you.
velocity is given as
when the object reached to its turning its velocity will be zero
so it will reach its turning at two time instant
Part b)
For acceleration we know that
now at t = 2
also at t=5
Answer:
Explanation:
from the question we are told that
Load
Force
Angle of inclination
Displacement
coefficient of kinetic friction
Answer: 3.65 m
Explanation:
from the question we have
angular speed = 33.3 rpm
coefficient of static friction (μ) = 0.3406
acceleration due to gravity (g) = 9.8 m/s^2
to get how far from the center of the turntable can the coin can be placed without having to slip off we equate the formula for the centrifugal force with the frictional force on the turntable force
mv^2 / r = m x g x μ
v^2 / r = g x μ .......equation 1
where
velocity (v) = angular speed (rads/seconds) x radius
we have to convert the angular speed from rpm to rads/seconds
angular speed (rads/seconds) = (2π / 60 ) x rpm
angular speed (rads/seconds) = ((2 x π) / 60 ) x 33.3 = 3.49 rads/ seconds
now
velocity = 3.49 x r = 3.49r
now substituting the value of velocity into equation 1
v^2 / r = g x μ
(3.49r)^2 / r = 9.8 x 0.3406
12.18 x r = 3.34
r = 3.65 m
