After that, they start to get shorter.
The day with the shortest daylight is the beginning of Winter.
After that, they start to get longer.
Their combined momentum after they meet is 0 .
Answer:
a = 7.5 m / s²
Explanation:
For this exercise let's use Newton's second law, let's create a coordinate system with the x axis parallel to the plane and the y axis perpendicular to the plane
Y axis
N - W cos θ = 0
N = mg cos θ
X axis
W sin θ = m a
mg sin θ = m a
a = g sin θ
let's calculate
a = 9.8 cos 40
a = 7.5 m / s²
I would have to see the graph.. but by looking at one one online, they are between points D and E.
