Answer:
Distance : 0.06533 meters or 65.33 mm
Step-by-step explanation:
To solve this problem we can make the forces equal when the system is at equilibrium.
mass
gravity ( constant ) = spring constant
where l = the length at which the rubber band is stretched
0.2 kg
9.8 m / s² = 30 N/m
1.96 kg
m / s² = 30 N/m
l = 1.96 kg
m / s² / 30 N/m = 0.06533 meters / 65.33 mm
The rubber band is stretched a distance of 0.06533 meters, or 65.33 mm.
