15.) In a control system, an accelerometer consists of a 4.65-g object sliding on a calibrated horizontal rail. A low-mass spring attaches the object to a flange at one end of the rail. Grease on the rail makes static friction negligible, but rapidly damps out vibrations of the sliding object. When subject to a steady acceleration of 0.850g, the object should be at a location 0.460 cm away from its equilibrium position. Find the force constant of the spring required...
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...
Question 7 Spring 1 has an equilibrium length of 10 cm, and Spring 2 has an equilibrium length of 12 cm. Both springs have the same spring constant, k. If W, is the work required to stretch Spring Ito a length of ll em, and W is the work required to stretch Spring 2 to a length of 13 cm, then which one of the following is true? A Wi>W B. W <W: C. W, = W
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...

2. cm then released. A50 gram mass at rest stretches a spring by 2.5 cm. The spring is further stretched by 1.4 a) b) Assuming simple harmonic motion (with no drag), what is the frequency of the spring? If the drag coefficient r was 10 Hz, what is the frequency of the spring? If the frequency of the spring is 3 Hz, what is the drag coefficient r? c) Note: The units of the coefficient of resistance 2mr are force...
2. Consider the following physical situation: A spring that obeys Hooke's Law and has a known/given spring constant k has been compressed to half of its equilibrium length. It's anchored at one end while the other end pushes (but is not attached to) a block of mass m in the horizontal direction. The block is initially held in place. Once released, the block accelerates to the right and achieves a final speed of ve at the point when it leaves...
2. Following problem 1, the same spring-mass is oscillating, but the friction is involved. The spring-mass starts oscillating at the top so that its displacement function is x Ae-yt cos(wt)t is observed that after 5 oscillation, the amplitude of oscillations has dropped to three-quarter (three-fourth) of its initial value.

In a hurry to digest this . Tks for the help (thumb up) 2. A mass of m kilograms (kg) is mounted on top of a vertical spring. The spring is L metres long when disengaged and the end not attached to the mass is fixed to the ground. The mass moves vertically up and down, acted on by gravity, the restoring force T of the spring and the damping force R due to friction: see the diagram below The...
