11. [1pt]
In order to study the long-term effects of weightlessness, astronauts in space must be weighed (or at least `massed'). One way in which this is done is to seat them in a chair of known mass attached to a spring of known force constant and measure the period of the oscillations of this system. The 39.1 kg chair alone oscillates with a period of 1.36 s, and the period with the astronaut sitting in the chair is 2.31 s. Find the force constant of the spring.

12. [1pt]

In order to study the long-term effects of weightlessness, astronauts in space must be weighed (or at least "massed"). One way in which this is done is to seat them in a chair of known mass attached to a spring of known force constant and measure the period of the oscillations of this system. The 35.6kg chair alone oscillates with a period of 1.30s , and the period with the astronaut sitting in the chair is 2.23s . Part A...

1. High-impact activities such as jogging can cause considerable damage to the cartilage at the knee joints. Peak loads on each knee can be eight times body weight during jogging. The bones at the knee are separated by cartilage called the medial and lateral meniscus. Although it varies considerably, the force at impact acts over approximately 11cm2 of this cartilage. Human cartilage has a Young's modulus of about 25 MPa (although that also varies). a.) By what percent does the...

As we've seen, astronauts measure their mass by measuring the period of oscillation when sitting in a chair connected to a spring. The Body Mass Measurement Device on Skylab, a 1970s space station, had a spring constant of 606 N/m. The empty chair oscillated with a period of 0.837 s . What is the mass of an astronaut who oscillates with a period of 2.25 s when sitting in the chair?

As we've seen, astronauts measure their mass by measuring the period of oscillation when sitting in a chair connected to a spring. The Body Mass Measurement Device on Skylab, a 1970s space station, had a spring constant of 606 N/m. The empty chair oscillated with a period of 0.840 s . a. What is the mass of an astronaut who oscillates with a period of 2.21 s when sitting in the chair?

It is important for astronauts in space to monitor their body weight. In Earth orbit, a simple scale only reads an apparent weight of zero, so another method is needed. NASA developed the body mass measuring device (BMMD) for Skylab astronauts. The BMMD is a spring-mounted chair that oscillates in simple harmonic motion (see figure below). From the period of the motion, the mass of the astronaut can be calculated. In a typical system, the chair has a period of...

The masses of astronauts are monitored during long stays in orbit, such as when visiting a space station. The astronaut is strapped into a chair that is attached to the space station by springs and the period of oscillation of the chair in a frictionless track is measured. a - The period of oscillation of the 14.0 kg chair when empty is 0.790 s. What is the effective force constant (in N/m) of the springs? b - What is the...
