Answer:
Option C: "The rock will slow down and eventually stop"
Explanation:
Since this is a real event, and not an ideal situation where there is no friction forces acting between the frozen pond and the rock, there is going to exist some force of dynamic friction (even small) acting between them. One can look up coefficients of dynamic friction between similar objects, and realize that some small force will be acting as the rock slides on the surface of the pond. That force acts always opposite the direction of movement, therefore decelerating the rock. The rock's speed will continue reducing in magnitude until it eventually stops.
Then, the selected answer is: "The rock will slow down and eventually stop."
The acceleration is the change of speed/velocity over time. Thus to calculate this you do (V1-V2)/T or (11.2-9.6)/4 or 0.4 m/s^2
For the first one it’s the guh sound

Answer:
2406 miles
Explanation:
Let A be the starting position, B the junction position and C the final position after flying the 3.5 hrs. Also, let b be the distance from the starting point:
#Distance traveled in 1.5hrs is;
#Distance traveled in next two hrs:
#Now using the Cosine Rule:
Hence, the pilot is 2406 miles from her starting position.
Im pretty sure it’s a because it makes more sense you know?.
