Answer to Question #58104 in Mechanics | Relativity for Christbeauty

Question

6 When a 30-g mass is hung from the end of a spring, the spring stretches 8.0 cm. The same spring with a mass of 200 g at at its end is stretched 5.0 cm, released and allowed to oscillate on a frictionless horizontal surface. Find the frequency of the oscillation.
0.54 Hz
0.68 Hz
0.34 Hz
9.5 Hz

7 The system shown is an example of the Atwood's machine. What is the acceleration of the masses? Assume the the pulley is frictionless and the rope massless. Take
g=9.8m/s2
4.2m/s2
7.4m/s2
9.8m/s2
3.3m/s2
