Answer:
C. newtons/meter
Explanation:
To find the units of spring constant you can use the hook's law, which says,
F = k × x where
F = force (unit Newton)
k = spring constant
x = expansion or contraction ( unit m)
So by this equation you can get that
k = F / X
So you get the units as N/m
The first one? If not I just guessed
Answer:
6 m/s²
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 30 m/s
Time (t) = 5 s
Acceleration (a) =..?
Acceleration is defined mathematically as:
Acceleration (a) = Velocity (v) /time (t)
a = v /t
With the above formula, we can obtain the acceleration of the object as follow:
Velocity (v) = 30 m/s
Time (t) = 5 s
Acceleration (a) =..?
a= v/t
a= 30/5
a = 6 m/s²
Therefore, the acceleration of the object is 6 m/s² due East.
Your answer should be A, because every reaction has an equal opposite reaction
