1. The problem statement, all variables and given/known data A 10.0kg mass undergoes Simple Harmonic Motion with an amplitude of 8.0 cm, a maximum acceleration of magnitude 3.26 m/s^2, and an unknown phase constant φ. What is the period, max speed of the mass, the total mechanical energy of the system, and the magnitude of the force on the particle when it is at half of its maximum displacement? 2. Relevant equations a=xm-w^2cos(wt+φ) 3. The attempt at a solution 3.26=8.0-w^2cos(wt+φ) what do i use for the w? How can we do this with out a phase.
