1. Harmonic oscillation and motion graphs. Oscillation with 1.2kg hanging mass M velocity {mfsi Above is the velocity graph of a weight oscillating on a spring through time. 3. Draw a rough sketch of the acceleration function superposed on the graph above {i.e. draw it on the graph} with proper labels. b. Describe and explain the relationship between the velocity and acceleration for the oscillating mass. c. Deduce the measured period of oscillation from the graph. how 1your calculation. d. Is there damping? How do you know? e. Calculate the spring constant [you may use the SHD formula for this part}
