Answer:
7.0 m/s
Step-by-step explanation:
We can solve this using the 2 kinematic equations and you can use either:
So let's use the first one.
Vi = initial velocity
Vf = final velocity
a = acceleration due to gravity (constant 9.8m/s²)
t = time
The marble is dropped so this means that it is in free fall. The initial velocity is always 0m/s.
We are given then the following:
d = 2.5m
t = 0.71s
Vi = 0 m/s
a = 9.8m/s²
So we plug in the values we know and solve:
answer is 130 use calculator
4w+5+33=90
4w=90-5-33
4w=52
w=13
Second graph, the other three are all the same(reflection) while number two is different and shows a translation
Answer:
Probably 5
Step-by-step explanation:
This is an extremely confusing question. Whoever wrote it most likely had a typo.
The little box in the corner of the triangle means that is 90 degrees. if that is the case, this is a simple question:
Apply pythagorean theorem (a^2 + b^2 = c^2)
In this case:
3^2 + 4^2 = x^2
x^2 = 25
x=5.
HOWEVER: the two given angles are 60 degrees and 50 degrees.
Which does not work. It creates an impossible triangle.
