Answer:
should stay away from trees, water, and tall objects.
Answer:
speed v = 0.148 m / s
velocity v = 0
Explanation:
In this exercise we must be careful that the speed is a scalar and the speed is a vector, let's start by looking for the speed
v = Δx /Δt
the distance traveled is x = 2d and the time taken is
t = 7h 30 min
let's reduce to seconds
t = 7 h 3600s / 1h + 30 min 60s / 1min = 27000 s
so the speed is
v = 2d / 27000
to finish the calculation suppose a distance traveled d = 2000 m
v = 2 2000/27000
v = 0.148 m / s
this is the raides which is the speed module
Velocity is a vector,
v = Dx / Dt
in this case the displacement is
Dx = d -d
Dx = 0
the total displacement is zero since it returns to the starting point, consequently the velocity is zero
v = 0
bold is a vector
Answer:
B
Explanation:
A is completely necessary, in fact citing your sources is important. So false.
B is correct, unreliable bad research is not good to use
C is incorrect because not everything may be truthful
D is not necessary because it may be disturbing to the reader.

Answer:
Explanation:
If a baseball is hit into the air with a velocity of 27 m/s, we want to determine the maximum height of the ball. Using the projecile formula;
Max height H = u²/2g
u is the initial velocity of the body = 27m/s
g is the acceleration due to gravity = 9.81m/s²
H = 27²/2(9.81)
H = 729/19.62
H = 37.16m
Hence the ball went 37.16m high
