Vertical Springs

4 Activities

A mass of 200 g200\ gis attached to a free vertical spring with k=5 Nmk=5\ \frac{N}{m} Then, it is set to oscillate with an initial downward velocity of 2 m/s2\ m/sfrom its original hanging position. Find the amplitude of this oscillation.

(Hint: first, use Newton's second law to determine the initial hanging position.)
More Vertical Springs Questions:
A mass of 100 g is attached to a vertical spring and it is at equilibrium. The mass is lowered by 10 cm and is released to oscillate. What is the spring constant if it takes 1 s to go from the lowest position to highest position in this oscillation?

Hooke's Law and Simple Harmonic Motion

Practice: Dropping putty on a spring frame
A 0.15 kg frame, when suspended from a coil spring, stretches the spring 0.070 m. A 0.200-kg lump of putty is dropped from rest onto the frame from a height of 30.0 cm (as shown). Find the maximum distance the frame moves downward from its initial position.

Vertical Springs Concept Clarifier
A spring with k=50 Nmk=50\ \frac{N}{m}and length 10 cm10\ cmis hanging from the ceiling (the spring is massless).
In this problem, to keep the math a bit simpler, feel free to use g=10m/s2g=10 m/s^2. (No penalty for using 9.81 if you want, though.)
a) If we attach a 50 g50\ gmass to the spring and then let it fall down, by how much does the spring stretch?
