A body of mass 0.60kg is connected to a spring and performs SHM with a period of 2.0s. At an instant when its displacement from equilibrium is 0.040m, the kinetic energy of the body is measured to be 0.18J.
a. (i) Find the amplitude of oscillation.
b. (ii) Calculate the force constant of the spring.
c. (iii) What is the total mechanical energy of the system?
