Answer:
3494444444.44444 J
-87077491.39453 J
Explanation:
M = Mass of Earth =
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
R = Radius of Earth =
h = Altitude =
m = Mass of satellite = 629 kg
v = Velocity of spacecraft =
The kinetic energy is given by
The spacecraft's kinetic energy relative to the earth is 3494444444.44444 J
Potential energy is given by
The potential energy of the earth-spacecraft system is -87077491.39453 J
16/9 m/s^2
negative 4/3 m/s^2
14 m/s
the last one is too detailed to do in my head while on the bus; sorry
Answer:
0-4 acceleration comes at 12 m/s where (B) stagnates at 12 m/s and remains for 4 seconds (C) is breaks being activated slowing the car to 6 m/s in 2 seconds and (D) over the course of 4 seconds brings the car to 10 m/s.
Explanation:
The smallest marble has the most kinetic energy therefore it would be the correct answer
The process that produces the energy radiated by stars is nuclear fusion in the core.
For a star on the main sequence, it's the fusion of hydrogen nuclei into helium.
