1. A pendulum is formed by taking a 1.0 kg mass and hanging it from the ceiling using a steel wire with a diameter of 1.1 mm. It is observed that the wire stretches by 0.05 mm under the weight of the mass. What is the period of oscillation of the pendulum?

2. 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 34.8 kg chair alone oscillates with a period of 1.45 s , and the period with the astronaut sitting in the chair is 2.25 s .

a.) Find the force constant of the spring.

b.) Find the mass of the astronaut.

Expert Solution

1) 1.977s

2)

a)

b) Mass of astronaut, M= 48.94Kg

An ideal spring is in equilibrium, hanging from a ceiling with a 1 kg mass at...

An ideal spring is in equilibrium, hanging from a ceiling with a 1 kg mass at the end. At rest, the length of the hanging spring is 10 cm. Then, an additional 5 kg block is added to the spring, causing its length at rest to increase to 13 cm. The 5 kg block is then removed. Starting from rest, when the 5 kg block is removed, the spring begins to oscillate. What will the spring’s velocity be, the third...

The following information applies to every part of this problem: A 1-kg mass hanging from a spring stretches it .3924 m in its equilibrium position. The spring is initially compressed to .5 m above the equilibrium point and released with an initial downwards velocity of 2 m/s. Use 9.81 m/s2 for the acceleration due to gravity. (a) Assuming that there is no damping and no additional force applied to the spring, write down and solve an initial value problem giving...
