Answer:
390 N
Explanation:
The net acceleration is:
a² = aₓ² + aᵧ²
a² = (900 m/s²)² + (870 m/s²)²
a = 1250 m/s²
So the net force is:
F = ma
F = (0.31 kg) (1250 m/s²)
F = 390 N
"Constant velocity" is another way of saying "zero acceleration".
Answer:
physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time
