A Mass on a Spring Vibrates in Simple Harmonic Motion

question 20

Multiple Choice

A mass on a spring vibrates in simple harmonic motion at a frequency of 4.0 Hz and an amplitude of 5.0 cm.If a timer is started when its displacement is a maximum (hence x = 5 cm when t = 0) ,what is the acceleration magnitude when t = 3 s?

• A) 31.6 m/s²
• B) 15.8 m/s²
• C) 10.5 m/s²
• D) zero
