Does it not tell you how long it took it to reach the ground? Constant Velocity should be distance over time
<h2>
Weight of astronaut 2450 miles above the Earth is 80.38 pounds</h2>
Explanation:
Given that gravitational force, F, between an object and the Earth is inversely proportional to the square of the distance from the object and the center of the Earth.

Where F is gravitational force between an object and the Earth, r is the distance from the object and the center of the Earth and k is a constant.
Radius of Earth = 4000 miles
In case 1 an astronaut weighs 209 pounds on the surface of the Earth,

Now we need to find weight of astronaut 2450 miles above the Earth
r = 4000 + 2450 = 6450 miles

Weight of astronaut 2450 miles above the Earth is 80.38 pounds
Answer:
This is the formula
Explanation:
−(0.54 m/s)2
2(−1.67 m/s2)
so this is the step by taking the mean of the maximum value of friction with the minimum value you can get the average force of friction
Every material in the world can be defined in terms of how well it conducts electricity. Certain things, such as cold glass, never conduct electricity. They're known as insulators. Materials which do conduct electricity, like copper, are called conductors. In the middle are materials known as semiconductors, which don't conduct as well as conductors, but can carry current. Last, are materials called superconductors, which when brought down to very low temperatures turn into superhighways of current -- they conduct electricity without any resistance whatsoever.
