The actual answer is: SA = 2rh + 2r2

The answer is not SA = 2lw + 2wh + 2lh, the other guy has it incorrect. I put his answer in an assignment and I got it wrong. Trust me, the correct answer is SA = 2rh + 2r2.

A 60 - kilogram person stands on a compression spring . The spring constant is 2500 Newtons per meter .

insens350 [35]

<h2>Answer:0.2352 $m$ </h2>

Step-by-step explanation:

Let the mass of the person be $m$ .

Let the spring constant be $k$ .

Let the displacement in spring be $x$

Let the acceleration due to gravity be $g$

As it is given that the person just stands,the forces are balanced.

So, $mg=kx$

Given,

$m=60Kg\\k=2500Nm^{-1}\\g=9.8ms^{-2}$

$60\times 9.8=2500\times x\\x=\frac{588}{2500}=0.2352m$

Solve for x: 12-2x=-2(y-x)

a_sh-v [17]

12 - 2x = -2(y - x)

12 - 2x = -2y - (-2x)

12 - 2x = -2y + 2x

12 - 2x - 2x = -2y + 2x - 2x

12 - 4x = -2y

12 - 12 - 4x = -2y - 12

-4x = -2y - 12

-4x/4 = -2y/4 - 12/4

-x = -0.5y - 3

-x/-1 = -0.5y/-1 - 3/-1

x = 0.5y + 3

or

x = 3 + 0.5y
