A Mass on a Spring Vibrates in Simple Harmonic Motion

question 57

Multiple Choice

A mass on a spring vibrates in simple harmonic motion at a frequency of 4.2 Hz and an amplitude of 4.2 cm.If a timer is started when its displacement is a maximum (hence x = 4.2 cm when t = 0) ,what is the acceleration magnitude when t = 4 s?
​

• A) zero
• B) 0.3 m/s²
• C) 18.1 m/s²
• D) 9 m/s²
• E) ​11.8 m/s²
