Answer:
(A) Acceleration will be [tex]1.145rad/sec^2[/tex]
(B) Coefficient of static friction will be 0.116
Explanation:
We have given angular speed
[tex]\omega =33rpm=\frac{2\pi \times 33}{60}=3.454rad/sec[/tex]
Distance from the axis r = 9.6 cm = 0.096 m
(a) Acceleration is equal to
[tex]a_c=\omega ^2r=3.454^2\times 0.096=1.145rad/sec^2[/tex]
(b) For seed is not to slip
[tex]ma=\mu mg[/tex]
[tex]\mu =\frac{a}{g}[/tex]
[tex]\mu =\frac{1.145}{9.8}=0.116[/tex]
So coefficient of static friction will be 0.116
