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!

Line are the supervisory people or those who provide logistic support for the police officers found on the field.

Ethnicity can be influenced by the factor of scale and place. Many ethnic people have been known to gather in places close to each other, forming what’s known as an ethnic enclave. Ethnic people tend to stick closer together in certain places and different scales. An example of this would be China Town which is found in New York, where many Chinese and other asian people stick close together because of similar cultures and differences compared to Americans.
