A uniform solid cylinder can roll without sliding on a horizontal surface as shown in the figure. The mass of cylinder is 10 kg and the spring constant for both the ideal springs is 300 N m - 1 . What is the angular frequency (in rad s - 1 ) of small oscillations of the centre of the cylinder?
Correct answer
10
Step-by-step solution
The total energy of the system is E = 3 4 m v 2 + 5 2 k x 2 d E d x = 3 2 m a + 5 k x = 0 a = - 10 k 3 m x ⇒ ω = 10 k 3 m = 10   rad   s - 1
