Oscillation with 1.2kg hanging mass OI .h M e E u 25 30 velocity {m/sl ii: an 6' in time (5) Above is the velocity graph of a weight oscillating on a spring through time. a. 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. Show your calculation. d. Is there damping? How do you know? e. Calculate the spring constant {you may use the SH0 formula for this part)
