At a certain distance from the center of the Earth, a 4.0-kg object has a weight of 3.1 N.

Find this distance.

If the object is released at this location and allowed to fall toward the Earth, what is its initial acceleration?

If the object is now moved twice as far from the Earth, by what factor does its weight change?

By what factor does its initial acceleration change?

Imagine dropping an object from a tall tower. If the Earth is moving in a certain direction through space at a speed of many kilometers per second, then it will move forward a considerable distance even during the short time before the object hits the ground. This means that since the earth moves forward under the object as it fall, the object will hit the ground a considerable distance away from the drop point. Construct an argument based on momentum...

P1:Suppose an object is launched from Earth with 0.52 times the escape speed. How many multiples of Earth's radius (RE = 6.37 x 106 m) in radial distance will the object reach before falling back toward Earth? The distances are measured relative to Earth's center, so a ratio of 1.00 would correspond to an object on Earth's surface. For this problem, neglect Earth's rotation and the effect of its atmosphere. For reference, Earth's mass is 5.972 x 1024 kg. Your...

A meteoroid with a mass of 5840 kg is detected heading toward the Earth, which has a mass of 5.98×1024 kg. Its speed at a distance of 3.85×108 m from the center of the Earth (roughly the distance to the Moon), is 1000 m/s. Fortunately, it misses the Earth by a distance of 9.77×106 m, measured from the Earth's center. How fast was the meteoroid traveling when it came closest to the Earth? The effects of the Sun's and Moon's...
