Mathematics: for a moving object, the force acting on the object varies directly with the objects acceleration. when a force of 90 n acts on a certain object, the acceleration of the object is 10 m/s2. if the force is changed to 72 n, what will be the acceleration of the object?

Equation of a tangent line of a curve is:y- y0 = f´ (x0) (x - x0 ). In this case: x0=1, y0=1f´(x)=(Derivation)f´(x0)=y - 1 = 1/2 ( x - 1 )y - 1 = 1/2 x - 1/2y = 1/2 x - 1/2 + 1y = ...

8 m/s^2

Step-by-step explanation:

F=kA

F=force

k=constant you will use for each F=kA relation

A=acceleration

Second sentence says F=90 while A=10 (plug in and find k)

90=k(10) so k=9

We have for any (A,F) that F=9A

Last sentence F=72, what is A?

So 72=9A which means A=8 m/s^2

Equation of a tangent line of a curve is:
y- y0 = f´ (x0) (x - x0 ). In this case: x0=1, y0=1
f´(x)= $\frac{1}{2 \sqrt{x} }$ (Derivation)
f´(x0)= $\frac{1}{2}$
y - 1 = 1/2 ( x - 1 )
y - 1 = 1/2 x - 1/2
y = 1/2 x - 1/2 + 1
y = $\frac{1}{2}x+ \frac{1}{2}$
