PLEASE HELP ME WITH THIS QUESTION!!!!!!
mr Goodwill [35]

From the table, y varies directly as x. Therefore,  the constant of variation is k = 2 and y = 2x.

<h3>How to find a direct variation?</h3>

For direct variation,

y ∝ x

Therefore,

y = kx

where

  • k = constant of proportionality

Hence,

(-2, -4)

-4 = -2k

k = -4 / -2

k = 2

(-4, -8)

y = -4(2) = -8

Therefore,

k = 2 and y = 2x

Suppose that 5 J of work is needed to stretch a spring from its natural length of 30 cm to a length of 39 cm.
vesna_86 [32]

Answer

given,

work = 5 J

spring stretch form 30 cm to 39 cm

W = \dfrac{1}{2}kx^2

x = 0.39 - 0.30 = 0.09 m

5 = \dfrac{1}{2}k\times 0.09^2

k = \dfrac{5\times 2}{0.09^2}

k = 1234.568 N/m

a) work when spring is stretched from  32 cm to 34 cm

x₂= 0.34 -0.30 = 0.04 m

x₁ = 0.32 - 0.30 = 0.02

W = \dfrac{1}{2}k(x_2^2-x_1^2)^2

W = \dfrac{1}{2}\times 1234.568 \times (0.04^2-0.02^2)^2

W = 0.741 J

b) F = k x

  25 = 1234.568 × x

     x = 0.0205 m

     x = 2.05 cm
