Must prepare a written exam when under investigation
Known Variables:
Δy = 1.5 m
v0 = 30m/s at 60° above the horizontal.
t = 4.0 s
a. vfy = v0y + at
0 = 30sin(60) + (-9.8)t
-25.98 = -9.8t
t = 2.65.
4-2.65 = 1.35s.
Δy = v0yt + at^2/2
Δy = 25.98(2.65) + (-9.8)(2.65)^2/2
Δy = 34.44 m
1.5 + 34.44 = 35.94 m.
Δy = v0t + at^2/2
Δy = (-9.8)(1.35)^2/2
Δy = -8.93.
35.94 - 8.93 = 27.01 m.
b. vfy = v0y + at
0 = 30sin(60) + (-9.8)t
-25.98 = -9.8t
t = 2.65.
Δy = v0yt + at^2/2
Δy = 25.98(2.65) + (-9.8)(2.65)^2/2
Δy = 34.44 m
1.5 + 34.44 = 35.94 m.
vfy = v0y + at
vfy = (-9.8)(1.35)
vfy = -13.23 m/s.
I might have gone wrong somewhere so please check my answer! Cheers!

If there’s suppose to be questions? Then
I think it would’ve been Africa?
Another way to describe location is to use reference lines to describe coordinates, or absolute position, on the globe. Two types of imaginary reference lines are used to locate positions or points and to make accurate globes and maps. These lines are called parallels of latitude and meridians of longitude.
Latitude and longitude make up the grid system that helps us identify absolute, or exact, locations on the Earth's surface. You can use latitude and longitude to identify specific locations. Latitude and longitude are also helpful in identifying landmarks.
