1. The problem statement, all variables and given/known data A 200g mass attached to a horrizontal spring oscillates at a frequency of 2.0 Hz. At one instant, the mass is at x=5.0cm and has vx = -30cm/s. A. Determine the period. T= ____seconds B. Determine the amplitude. A =____cm C. Determine the maximum speed. vmax = ____ cm/s D. Determine the total energy. ____ J 2. Relevant equations A. T = 1/frequency B. ???? C. vmax= 2(pi)(f)(A) = 2piA/T D. ???? Others: deltaL = mg/k where k=spring constant 3. The attempt at a solution A. Answer = 0.5 seconds from T = 1/f.... T = 1/(2.0Hz).... T=0.5 secods B. C. vmax=2pi(2.0Hz)(A) D. I'm not looking for just the answers; I am in desperate need of an explanation of HOW to do the problem. Any help is greatly appreciated!!!
