Answer to Question #61863 in Mechanics | Relativity for Blessed

Question

7 The system shown is an example of the Atwood's machine. m1 and m2 are connected by a light inextensible string over a light and smooth pulley with m1>m2. What is the acceleration of the masses?

12 A long light steel strip is clamp at the lower end and a 2.0-kg mass is fastened to the top end as shown in the figure. A horizontal force of 8.0 N is required to displace the mass to 20 cm one side. Assuming that the system undergoes simple harmonic motion when released, calculate the period of oscillation of the mass.
