An elastic string of negligible mass has one end fixed to a ceiling at point A. The other end, point B, which is attached to a particle of mass 3 kg, is in a position such that it is vertically below point A, with the distance AB equal to 0.7 m. The mass is released from rest. If the modulus of elasticity of the string is 35 N and its natural length is 1.3m find i) The distance of the mass below point A when the mass first comes to rest again. ii) The distance of the mass below point A when it is at rest in its final equilibrium position.

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.

A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass.
A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass. At time t = 0 the mass is released from rest at a distance d = 0.35 m below its equilibrium height and undergoes simple harmonic motion with its position given as a function of time by y(t) = A cos(wt - φ). The positive y-axis...

NEED ASAP One end of a vertical 360 N/m spring is attached to the ceiling and the other end is attached to a 24 kg mass. The mass is released from rest when the spring is at equilibrium length. The mass falls 1.2 m before again coming to rest, how much mechanical energy is lost during this fall?

A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.71 m. With the string hanging vertically, the object is given an initial velocity of 1.6 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point where the string makes an angle θ with its initial vertical orientation and then swings...

A particle of mass m and of negligible dimensions is fixed to the end of a uniform slender bar of mass m and length L. The compound particle-bar is released from rest in the vertical position (O=0) and given a slight nudge such that the center of its square end pivots about the corner o. The bar is observed to slip when the angle reaches the critical value 0=6c. YOUR CHOICE: Use the following parameter values: m=0.25kg, L=0.75 m &...

A massless spring hangs from the ceiling with a small object attached to its lower end. The object is initially held at rest in a position yi such that the spring is at its rest length. The object is then released from yi and oscillates up and down, with its lowest position being 14 cm below yi. (a) What is the frequency of the oscillation? (b) What is the speed of the object when it is 12 cm below the...

A 1.0 kg mass is attached to a string wrapped around a shaft of negligible mass and having a 5.0 cm radius. A dumbbell-shaped "flywheel" made from two .500 kg masses is attached to one end of the shaft and perpendicular to its axis. The mass is released from rest and allowed to fall .8 m to the floor. It reaches a speed of 1.5238 m/s just before striking the floor. How far apart are the masses of the dumbbell?

A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.79 m. With the string hanging vertically, the object is given an initial velocity of 2.1 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point where the string makes an angle θ with its initial vertical orientation and then...
