This procedure has been used to “weigh” astronauts in space: A 42.5 kg chair is attached to a spring and allowed to oscillate. When it is empty, the chair takes 1.30 s to make one complete vibration. But with an astronaut sitting in it, with her feet off the floor, the chair now takes 2.54 s for one cycle. What is the mass of the astronaut?

An object of unknown mass is attached to an ideal spring with force constant 110 N/m and is found to vibrate with a frequency of 5.50 Hz. Part A Find the period. Express your answer in seconds. Part B Find the angular frequency. Express your answer in radians per second. Part C Find the mass of this object. Express your answer in kilograms.

There are more than 300 species of hummingbirds in the world and about 10 species regularly breed in the United States. One of which is the Ruby-throated Hmmingbird who can flap its wings with an angular speed of 332 rad/s. Calculate the period of its flapping motion.

Answer must be in scientific notation with SI units that do not have prefixes except for kg. (m/s not cm/s). Answer must be in standard form scientific notation. All angles are to be calculated to the nearest 0.1 deg (tenth of a degree).

The smooth hollow tube assembly rotates about a vertical axis with angular velocity ω=θ˙=3.8ω⁢=θ˙=3.8 rad/s and ω˙=θ¨=−2.4ω˙=θ¨=-2.4 rad/s2. A small 0.23-kg slider P moves inside the horizontal tube portion under the control of the string which passes out the bottom of the assembly. If r=0.88r=0.88 m, r˙=−1.9r˙=-1.9 m/s, and r¨=3.8r¨=3.8 m/s2, determine the tension T in the string and the horizontal force Fθ exerted on the slider by the tube. T is positive in tension, and Fθ is positive if in the positive θ direction.

Babalik pa rin. A block attached to a spring oscillates back and forth on a frictionless surface with a period of To. If the angular frequency was doubled, what would be its period of oscillation?? O To/2 O To 2To O √2To

A coin having a mass of m = 12 g, a thickness of h = 0.17 cm, and a radius of r = 1.5 cm has a small hole drilled through it so that it can be suspended from a thin wire and worn as an earring or pendant. The hole is at a distance of 7/8 r from the center of the coin as shown above. When suspended from this hole, the coin is a physical pendulum that swings back and forth with this hole as its axis of rotation. Assuming that the hole does not appreciably change the center of mass of the coin, determine the period of this physical pendulum.
