The period of oscillation of a block of unknown mass hung from a spring is 1.8 s. A. What would be the period of another system with the same spring but the block having a mass 4 times the original block? B. What would be the period of yet another system with a spring which is twice stiffer (i.e., k value is double) and the block having a mass double of the original block? C. What is the spring constant of the original system if the mass is 200 grams?
