Answer:
acceleration would be 9 meters per second squared
Step-by-step explanation:
If quantity "A" varies directly with quantity "B", then we can write:
A = kB
Now, this problem says that force (f) varies directly with acceleration (a). So we can write:
f = ka
Given f = 100 and a = 10, so we substitute and find k (the proportionality constant). Shown below:
f = ka
100 = k(10)
k = 100/10
k = 10
So, we have
f = 10a
Now, force is 90, so what's the acceleration?
90 = 10a
a = 90/10
a = 9
So, the acceleration would be 9 meters per second squared
step 1
we have the curve
Find out the derivative
step 2
Find out the equation of the line perpendicular to the given curve that passes through the point (0,8)
Remember that
If two lines are perpendicular, then their slopes are negative reciprocal
so
The slope of the perpendicular line is m=-1/2
The equation of the line is given by
where
m=-1/2
point (0,8) ----> y-intercept
substitute
step 3
Find out the intersection of both lines
Equate both equations
Find out the y-coordinate of the point
<h2>The coordinates of the point are</h2>
