Question: Suppose you have a block resting on a horizontal smooth surface. the block (mass m) is attached to a horizontak spring (spring constant k) which is fixed at one end. the mass is pulled to one side and released.this 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 velocity and acceleration of the motion. on the graphs, label the max values of velocity and acceleration
c) draw the graph for KE and calculate and label the max value of kinetic energy on the graph
d) Draw the graph for elastic potential energy and calculate and label on the graph the max value of elastic pe
e) calculate the numerical value and draw the graph for the total energy
