A mass of 0.10 kg is attached to aspring. It is pulled 200 mm to theright of its position when thespring is neither stretched norcompressed, and then releasedfrom rest. The resulting freevibrations, which are damped byfriction, have a frequency of 2.0Hz. It is observed that each swingto the right takes the mass to apoint 30 mm to the left of itsprevious limit. The mass finallycomes to rest 235 mm to the leftof the point from which it wasreleased, (a) Calculate the force ofsliding friction Fst. (b) Calculateupper and lower limits for theforce of sticking friction Fst

Aweight is attached to a spring and is suspended from a ceiling so that it lies 30 cm from the ceiling when it is at rest. The spring is stretched so that the weight is 38 cm from the ceiling and is then released. It bounces up and down for a while. Each time it comes to the bottom of its bounce, the length of the stretch is 75% of the previous stretch. a) The period of each oscillation (bounce) is 1/2 second. Write an equation that represents the distance from the weight to the ceiling. b) Draw a graph of the function. c) Without doing any calculations, state the distance of the spring from the ceiling after 1 minute
A 3-kg mass is attached to a spring with stiffness 60 N/m. The damping constant for the system is 12√5 N-sec/m. If the mass is pulled 20 cm to the right of equilibrium and given an initial rightward velocity of 4 m/sec, what is the maximum displacement from equilibrium that it will attain?
Two particles oscillate in simple harmonic motion along a common straight-line segment of length 1.1 m. Each particle has a period of 1.4s, but they differ in phase by T/7 rad. (a) How far apart are they 0.31 s after the lagging particle leaves one end of the path? (b) Are they then moving in the same direction, toward each other, or away from each other? (a) Number (b) i Units
The human eardrum responds to sound by vibrating. If the eardrum moves in simple harmonic motion at a frequency of 4.22 kHz and an amplitude of 0.110 nm (roughly the diameter of a single hydrogen atom), what is its maximum speed of vibration? (Amazingly, the ear can detect vibrations with amplitudes even smaller than this!) μm/s
A mass on a spring is held at a distance of 0.05 m from the equalibrium position. It is then released at time t=0 and undergoes simple harmonic motion. If the mass was 0.2 kg and the spring constant k was 6 Nm-1, what is the velocity of the mass at time = 7 seconds?
At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into oscillatory motion with an amplitude of 20.0 cm. It is observed that the maximum speed of the bunch of bananas is 42.2 cm/s. What is the weight of the bananas in newtons?
A spring hangs from the ceiling with an unstretched length of xo = 0.49 m. A mị = 8.3 kg block is hung from the spring, causing the spring to stretch to a length xị = 0.80 m. Find the length x2 of the spring when a m2 = 1.7 kg block is hung from the spring. For both cases, all vibrations of the spring are allowed to settle down before any measurements are made. m2 X2 = т,
A 1000 kg car carrying four 80 kg persons is traveling over “washboard" speed bumps spaced at regular intervals. The bumps are located 4 m apart. The car is observed to bounce with maximum amplitude when its speed is 16 km/h. The car now stops and the four people get out. By how much does the car body rise on its suspension owing to the decrease in weight?
