A 81.0-kg daredevil exhibitionist hangs on to the end of a long bungee cord attached to the railing of the Brooklyn Bridge and oscillates vertically. (Do NOT try this!) The spring constant of the bungee cord is 148 N/m, and the system\'s damping constant is 0.112 kg/s. How long does it take for the oscillation amplitude to decrease to 94.3% of its initial value?
What is the frequency of oscillation?
If the ball is released from rest at a height of 0.78m above the bottom of the track on the no-slip side, what is its angular speed when it is on the frictionless side of the track? suppose the ball is a solid sphere of radius 2.3cm and mass 0.14k..
How much time does the object take to reach the ground.
does the non-Coulomb electric field curl clockwise.
Assume that the volume of the empty spaces between the candes is negligible. If the height of the candes in the container increases at the rate of 0.270 cm/s, at what rate (kilograms per minute) does the mass of the candies in the container increa..
When the projectile is at the top of its trajectory, an internal explosion causes it to separate into two fragments of equal mass. One of the fragments falls straight downward as though it had been free from rest.
A beam of electrons passes by a single slit and a beam of protons passes by a second, but identical slit. If the electrons and protons have the similar speed, that beam would experience the greatest amount of diffraction? Clarify your answer.
Consider an experiment where a subject lands during two conditions from a height of 0.2 m. During the first landing condition, the subject lands 'stiffly' (e.g., very little knee flexion).
An organ pipe is open at one end and closed at the other. The pipe is designed to produce the note middle C, What is the frequency of the second harmonic
our little sister builds 2 tree houses and stretches a rope between them for sending messages to other tree house. She hangs a mass of 1.4kg on one end of the rope that passes over the pulley.
A 4.70 kg mass causes a vertical spring to stretch 0.850 meters. The spring is after that stretch and extra 0.270 meters and release (as a stopwatch starts) causing the spring and mass to oscillate.
The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find out the final speed of puck A also Find out the final speed of puck B. m/s
