When a laboratory sample of unknown mass is placed on a vertical spring-scale having a spring constant of 467 N/m, the system obeys the equation y = (4.4 cm) cos(33.3 s-1 t). What is the mass of this laboratory sample?
 
  What will be an ideal response?

Question 2

A 1.15-kg beaker (including its contents) is placed on a vertical spring scale. When the system is sent into vertical vibrations,
 
  it obeys the equation y = (2.3 cm)cos(17.4 s-1 t). What is the spring constant of the spring scale, assuming it to be ideal?
