1. The problem statement, all variables and given/known data A 130 g ball attached to a spring with spring constant 3.0 N/m oscillates horizontally on a frictionless table. Its velocity is 17 cm/s when x = 4.2 cm Find the: -Amplitude of Oscillation -Max acceleration -Speed of the ball when x = 2.8cm 2. Relevant equations T = 2*pi*(m/k)1/2 Sinusoidal equations for position and velocity of a particle in SHM 3. The attempt at a solution I'm not entirely sure where to start. I solved the velocity and position equations for t and set them equal to solve for A, but finding an intersection for that is beyond me. Not sure how else to work the equation. I figured if I could find A then I could take the derivative of the velocity equation and try to solve for the maximum acceleration, but that still leaves the phase shift and doesn't give an acceleration value to set it equal to. Not sure where to begin on this one at all.
