The free-fall acceleration on the moon is $1.62 \mathrm { m } / \mathrm { s } ^ { 2 }$. What is the length of a pendulum whose period on the moon matches the period of a 2.00-m-long pendulum on the earth?

When you drive your car over a bump, the springs connecting the wheels to the car compress. Your shock absorbers then damp the subsequent oscillation, keeping your car from bouncing up and down on the springs. as we discussed earlier shows real data for a car driven over a bump. We can model this as a damped oscillation, although this model is far from perfect. Estimate the frequency and time constant in this model.

A child on a swing set swings back and forth with a period of $3.3 \mathrm{~s}$ and an amplitude of $25^{\circ}$. What is the maximum speed of the child as she swings?

A mass on a string of unknown length oscillates as a pendulum with a period of 4.00 s. What is the period if a. The mass is doubled? b. The string length is doubled? c. The string length is halved? d. The amplitude is halved? Parts a to d are independent questions, each referring to the initial situation.

A block of mass 3.00 kg is placed against a horizontal spring of constant k = 875 N/m and pushed so the spring compresses by 0.070 0 m. If the block is now released and the surface is frictionless, calculate the bloc k' s speed after leaving the spring.

A sinusoidal wave has period 0.20 s and wavelength 2.0 m. What is the wave speed?

Determine the period of a 1.3-m-long pendulum on the Moon.

The free-fall acceleration on the surface of the Moon is about one-sixth that on the surface of the Earth. The radius of the Moon is about 0.250RE (RE = Earth’s radius = $6.37 \times 106$ m). Find the ratio of their average densities, ρMoon/ρEarth.

Return to the image of The Beaune Altarpiece on page 22. How does the emphasis on universal truth and everlasting punishment and reward make Christianity different from animism? How might faith in such a religious system shape the values and priorities of believers?

In "Theme for English B," the speaker says that he and the instructor are part of each other. What does he mean? Explain.

The free-fall acceleration on the surface of Jupiter, the most massive planet, is $24.79 \mathrm{m} / \mathrm{s}^{2}$.Jupiter’s radius is $7.0 \times 10^{4} \mathrm{km}$.Use Newtonian ideas to determine Jupiter’s mass.

The mass in a pendulum clock completes one complete swing in 1.00 s. What is the length of the rod?

We can model the motion of a bumblebee's wing as simple harmonic motion. A bee beats its wings 250 times per second, and the wing tip moves at a maximum speed of 2.5 m/s. What is the amplitude of the wings tip's motion?

A 200 g air-track glider is attached to a spring. The glider is pushed 10.0 cm against the spring, then released. A student with a stopwatch finds that 10 oscillating take 12.0 s. What is the spring constant?
