Instantaneous 37201

The amplitude of the linear undamped harmonic oscillator is A = 12 cm, and the frequency f = 15 Hz. What is its instantaneous deflection at time a) t1 = 0.02s, b) t2 = 0.04s, when it was zero at time t = 0 s?

Correct answer:

y1 =  11.4127 cm
y2 =  -7.0534 cm

Step-by-step explanation:

A=12 cm f=15 Hz ω=2π f=2 3.1416 1594.2478 1/rad  t1=0.02 s y1=A sin(ω t1)=12 sin(94.2478 0.02)=11.4127 cm
t2=0.04 s y2=A sin(ω t2)=12 sin(94.2478 0.04)=7.0534 cm
