3. {A-5} A mass is suspended by a spring such that it hangs at rest 0.5 m above the ground. The mass is raised 40 cm and released at time t = 0 s, causing it to oscillate sinusoidally. If the mass returns to the high position every 1.2 s, determine the height of the mass above the ground at t = 0.7 s. 3. {A-5} A mass is suspended by a spring such that it hangs at rest 0.5 m above the ground.
