Answer:
67.6 m
Explanation:
For this problem, we just need to analyze the motion of the two planes after the collision.
The two planes stick together and move with a velocity of
u = 19.3 m/s
The problem tells us that they skid until they stop: so, their final velocity is
v = 0
Since the velocity is not constant, this means that they are accelerating.
We also know that they skid for a time of
t = 7 s
Therefore, we can find their stopping distance using the following suvat equation
And substituting, we find
Answer:
see below
Explanation:
acceleration = Δv /Δt
for this situation 60 / 10 = 6 m/s^2
B) vf = vo + at
vf = 0 + 6(3) =<u> 18 m/s after 3 seconds </u>
<u />
C) vf = at
60 = 6 ( t) t = 10 seconds ( actually, this was given)
d = 1/2 a t^2
= 1/2 (6) (10)^2 = <u>300 m </u>
<u />
One atom on nitrogen because there isn’t a number directly after it’s the 3 signifies that there is three groups of those atoms as a total
