An ideal spring is in equilibrium, hanging from a ceiling with a 1 kg mass at the end. At rest, the length of the hanging spring is 10 cm. Then, an additional 5 kg block is added to the spring, causing its length at rest to increase to 13 cm. The 5 kg block is then removed. Starting from rest, when the 5 kg block is removed, the spring begins to oscillate.
What will the spring’s velocity be, the third time it returns to a length of 13 cm? Express your answer in units of m/s, but enter only the numeric answer

An ideal spring dangles from the ceiling at its relaxed length of 5 cm. A 3-kg mass is carefully hung from the end of the spring while the spring is relaxed, and then the mass is released from rest at time t = 0, which begins to stretch the spring. The spring stretches to its maximum length at time t = 130 ms when the mass reaches its lowest point. Then the mass returns upward, shortening the spring. The oscillation...

A spring is hanging from the ceiling. When a 2 kg mass is hung from the spring, the spring has a total length of 50 cm. When a 5 kg mass is hung from the spring, the spring has a total length of 70 cm. Determine the spring's relaxed length and its spring's spring constant. (You should keep 4 decimals in your values to avoid rounding errors.)
A spring with spring constant 350 N/m hangs from the ceiling.
James Bond attaches a block of mass 0.7 kg to the unstretched
spring and releases it from rest.
(Part A) How far below the starting point does the block fall
before coming momentarily to rest? Answer in cm

a block of mass 1.5kg is suspended from the ceiling by
a spring with a spring constant k=15N/m. a force of 20N is applied
to the block in the +y-direction thereby compressing the spring
(see picture). the block is initially at rest. at time t=0, the
force is removed and the block starts to oscillate down and up.
what is the amplitude of the oscillation?
g constant k 15 Nm. A force of see picture. The block is
Q2. A mass of 300 g is attached to a spring hanging from the ceiling. The spring stretches 20 cm when the mass is added. What is the spring constant of the spring? If the mass is now pulled 8 cm below it’s new equilibrium position, what will be the frequency of the oscillation What is the maximum speed of the mass? At what position will it have a speed that is one third of the maximum speed? What is...
A mass of 0.301 kg is attached to a spring hanging from a ceiling. The mass oscillates with a period of 1.41 seconds. What mass must be added to the orginal 0.301 kg mass in order to increase the period to 1.88 seconds? (in kg) A: 2.34x10 B: 3.39x10-1 C: 4.92X101 D: 7.14x10 E: 1.03 F: 1.50 G: 2.18 H: 3.15 Se Tries 0/20
1. A 10 kg box is at rest at the end of an unstretched spring with constant k-4000N/m. The mass is struck with a hummer giving it a velocity of 6.0m/s to the right across a frictionless Surface. What is the amplitude of the resulting oscillations of the system? (a) 2m (b) 0.6m (c) 0.5m (d) 0.4m (e) 0.3m 10 kg 2. When a 0.20kg block is suspended from a vertically hanging spring it stretches the spring from its original...
A block of mass mmm= 3.00 kg is attached to the end of an ideal spring. Due to the weight of the block, the block remains at rest when the spring is stretched a distance hhh= 8.00 cm from its equilibrium length. (Figure 1)The spring has an unknown spring constant k. Take the acceleration due to gravity to be g = 9.81 m/s2m/s2 . Suppose that the block gets bumped and undergoes a small vertical displacement. Find the resulting frequency...
An ideal spring hangs from the ceiling. A 1.25 kg mass is hung from the spring, stretching the spring a distance d = 0.0865 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0285 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position?
