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 288-kg mass, when attached to the end of a spring hanging vertically, stretches the spring 8 m.

A massless spring is hanging vertically from the ceiling. A mass m is attached to the bottom end of the spring and released from rest. How close to its final resting position is the mass when βt = 1 given that the mass finally comes to rest a distance d below the point from which it was released and the oscillator is critically damped.
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...
A spring is hanging from a ceiling with 50g mass attached. When the mass is pulled down from the equilibrium and released, it oscillates with 0.4s period. The spring constant is equal to
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
A mass weighing 96 lb is attached to a spring hanging from the ceiling and comes to rest at its equilibrium position. At time t = 0, an external force of F(t) = 3 cos 3t lb is applied to the system. If the spring constant is 15 lb/ft and the damping constant is 4 lb-sec/ft, find the steady-state solution for the system. Use g = 32 ft /sec. The steady-state solution is y(t) = | |
2. (35 points) A pendulum consists of a point mass (m) attached to the end of a spring (massless spring, equilibrium length-Lo and spring constant- k). The other end of the spring is attached to the ceiling. Initially the spring is un-sketched but is making an angle θ° with the vertical, the mass is released from rest, see figure below. Let the instantaneous length of the spring be r. Let the acceleration due to gravity be g celing (a) (10...
Problem 6. A mass of 1.00 kg is hung from the ceiling by an ideal spring. When a mass of 0.500 kg is added to the original mass, the spring stretches by an additional 0.933 cm. (a) What is the force constant of the spring? (b) By how much did the spring stretch when only the 1.00kg mass was hung from it? The system (with the 1.50kg mass) is now set in oscillation with an amplitude of 2.20cm. (c) What...
