Answer:
see that the correct one is D
Explanation:
In this problem the satellite is subjected to the universal force of attraction
F = G M m / r²
using Newton's second law with centripetal acceleration you can find the angular velocity of the satellite
F = m a
F = m w² r
G M / r³ = w²
and w = 2π / T
In this case, the satellite is in a two-dimensional movement, where the free fall of the satellite is compensated by the horizontal displacement, for which it is always at a distance from the earth, remaining at the same point.
When reviewing the different statements we see that the correct one isD
Velocity is the ratio of the distance covered and the time taken to cover that distance. So in this case velocity is 12km divided by 2 hours or 12000 meters divided by 7200 seconds, which comes out to be 1.66. So the velocity, in this case, is 1.66 m/s (meter per second)
Answer:
7664.06249 N/m
Explanation:
m = Mass of mug = 0.5 kg
x = Compression of spring = 0.08 m
h = Height of fall = 5 m
g = Acceleration due to gravity = 9.81 m/s²
The kinetic energy of the spring and potential energy of the fall are conserved

The spring constant of the spring is 7664.06249 N/m
