The graph shows the displacement of the block as a function of time. The maximum displacement is 15 cm.
a) If k = 150 N/m, calculate the mass of the block.
b) Draw the graphs for the velocity and acceleration of the motion. On the graphs, label the maximum values of velocity and acceleration, respectively.
c) Draw the graph for the kinetic energy and calculate and label on the graph the maximum value of KE.
d) Draw the graph for the elastic potential energy and calculate and label on the graph the maximum value of the elastic PE.
e) Calculate the numerical value and draw the graph for the total energy.
