A pendulum of length 2 meters is taken to the moon. if this pendulum makes 10 oscillations in 32.0 seconds, what is the value of gravitational acceleration on this moon?

a. 3.86 m/s^2
b. 2.54 m/s^2
c. 7.71 m/s^2
d. 9.86 m/s^2

Solution Summary

The solution calculates gravitational acceleration on moon.

1. How would you describe the change in velocity each second for an accelerating object?
2. How would you describe the amount of distance fallen each second for an accelerating object?
3. a) Is there gravity on the Moon?
b) What would happen if you doubled the mass of the object that is falling to the surface?

In his novel "From the earth to the moon", Jules Verne imagined that astronauts inside a space ship would walk on the floor of the cabin when the force exerted on the ship by the earth was greater than the force exerted by the moon. When the force exerted by the moon was greater he thought the astronauts would walk on the ceili

Ocean tides are produced primarily by the gravitational attraction of the Moon. Explain how this attraction gives rise to two tidal "bulges" on opposite sides of the Earth, resulting in two daily high tides and two daily low tides. [hint: Consider the inverse-square relationship of the distance in the gravitational force actin

A lunar landing craft needs to hover just above the surface of the moon, which has a gravitationalacceleration of (1/6) g. The exhaust velocity is 2000m/s but fuel amounting to only 20% of the total mass can be used.
How long can the landing craft hover?

Find the mass and the radii of the planets Mercury, Neptune and Pluto, masses in kilograms and radii in meters. With that data calculate the gravitationalacceleration on each of the planets in kilograms and meters and show the gravitationalacceleration in meters per square second. With the gravitationalacceleration from abo

At a certain instant, the earth, the moon, and a stationary 1470 kg spacecraft lie at the vertices of an equilateral triangle whose sides are 3.84 x 10^5 km in length.
a) Find the magnitude of the net gravitational force exerted on the spacecraft by the earth and moon. Find in N.
b) Find the direction of the net gravitati

The Moon revolves arond the earth in 27.3 days in a nearly circular orbit with a radius of 3.8 x 10^5 km. Assuming that the Moon's orbital motion is a uniform circular motion, what is the Moonacceleration as it "falls" toward the earth?

Q. Bouncing a ball:
Let g be the acceleration of gravity near the Earth's surface. The acceleration of gravity near the surface of the Moon is (approximately) g/6. Using the law of conservation of energy, i.e. the principle of conservation of energy, solve the following.
(a) Suppose that a ball is dropped from 9 feet above
