Small object of mass m is placed on the inner surface of the conical dish which can rotate with angular speed ω.
For μ=0.3 calculate the minumum and the maximum ω such that the object is remains at rest. Solve the problem using the indicated axes x-y.
Do the following steps:
(a) Show all forces acting on the object and and the acceleration
(b) Write Newton’s second law along both axes and solve.
The Attempt at a Solution
I have plugged in numbers and got answers for ωmax and ωmin but I dont get the right answer.
I have solved it right when I choose axis the ordinary X-Y axis but I need to know how to solve with using the other axis mentioned in the problem
The right answer is
ωmax=7.214 rad/s and ωmin =3.405 rad/s
