- Homework Statement
- The two blocks I and II shown above have masses m and 2m respectively. Block II has an ideal massless
spring attached to one side. When block I is placed on the spring as shown. the spring is compressed a distance
D at equilibrium. Express your answer to all parts of the question in terms of the given quantities and physical
constants.
a. Determine the spring constant of the spring
- Relevant Equations
- kx=mg
mgh=1/2kx^2
i attempted this problem by using conservation of energy,
mgh=1/2kx^2
mgD=1/2kD^2
2mg=kD
k=2mg/D
why is it wrong ? btw the correct answer used mg = kx which is mg/D
