You said that she's losing 1.9 m/s of her speed every second.
So it'll take
(6 m/s) / (1.9 m/s²) = 3.158 seconds (rounded)
to lose all of her initial speed, and stop.
Jet streams are tied to global warming so I’m guessing hotter
The answer is C. replacement
This would be an example of a replacement type of reaction. As the iron is replaced with the aluminum in the reaction.

Answer:
The kinetic energy of the baseball is 107.83 J
Explanation:
Given;
mass of the baseball, m = 144 g = 0.144 kg
velocity of the baseball, v = 38.7 m/s
The kinetic energy of the baseball is given by;
K.E = ¹/₂mv²
where;
m is mass of the object
v is speed of the object
K.E = ¹/₂(0.144)(38.7)²
K.E = 107.83 J
Therefore, the kinetic energy of the baseball is 107.83 J
