SUMMARY

The discussion centers on calculating the time taken for an object in Simple Harmonic Motion (SHM) to move from x=0 cm to x=5.78 cm, given a period of 5.73 seconds and an amplitude of 10.47 cm. The user correctly identifies the equation x=Acos(wt+φ) and calculates the phase constant φ as π/2. However, the user encounters difficulties in solving for time t after determining the angular frequency ω using the formula ω=2π/T, where T is the period. The community confirms the approach but requests clarification on the values obtained for ω and t.

PREREQUISITES
  • Understanding of Simple Harmonic Motion (SHM)
  • Familiarity with trigonometric functions and their inverses
  • Knowledge of angular frequency calculation
  • Ability to manipulate equations involving cosine functions
NEXT STEPS
  • Calculate angular frequency ω using the formula ω=2π/T for T=5.73 s
  • Use the inverse cosine function to find the angle corresponding to x=5.78 cm
  • Solve for time t using the rearranged equation from x=Acos(wt+φ)
  • Explore the implications of amplitude and phase constant on SHM calculations
USEFUL FOR

Students studying physics, particularly those focusing on oscillations and wave mechanics, as well as educators looking for examples of SHM problem-solving techniques.

Homework Statement



An object in SHM oscillates with a period of 5.73 s and an amplitude of 10.47 cm. How long does the object take to move from x=0 cm to x=5.78 cm?


Homework Equations



x=Acos(wt+ro)

The Attempt at a Solution


I solved for ro which was pi/2 when x=o and t=o. Then I solved for angular speed which was 2pi*frequency. Then I did cos^-1(5.78/10.47)=wt+pi/2 and I solved for t but that did not work. Could you please help me? Thank you.

Your equation looks correct.

What did you get for w and t?
