A mass 0.2kg attached to the lower end of a light helical spring produces an extension of 0.05m. Calculate the force constant of the spring. The mass is pulled down a further 0.02m and released. Calculate the time period of subseuent oscillations and the maximum value of the accelartion during motion. Assume g =10ms^-2. I am struggling with all parts of the uestion - please can you outline a method for me to follow. Thanks alot.
