Answer: work is done in stretching it from 5.0in. to a length of 12.8in is 36 lb.In
Step-by-step explanation:
We know that
f(x) = kx
given that;
Natural length L = 5
x = 8.4 - 5 = 3.4
force F = 4.0 lb
f(x) = kx
we substitute
4 = k × 3.4
k = 4 / 3.4
k = 1.1764 = 20/17
Now work done from natural length to 12.8
x = 12.8 - 5 = 7.8
work done = ₀∫^7.8 f(x) dx
= ₀∫^7.8 kx dx
we substitute value of k
= ₀∫^7.8 (20/17)x dx
= 20/17 [ x²/2 ]
= 20/17 [ (7.8)²/2 - 0 ]
= 1.1764 × 30.42
= 35.786 ≈ 36 lb.In
Therefore work is done in stretching it from 5.0in. to a length of 12.8in is 36 lb.In
To find h, we gotta do reverse bedmas or pemdas !!
301.6= 3.14*h/3
first, we bring the 3 to the other side, to do that, we must perform the opposite operation. The 3 is being divided on this side, meaning we must multiply by 3 on both sides to get rid of it.
301.6 (3) =3.14*h (3) /3
904.8= 3.14 *h --------------(the 3's on this side are gone because they cancel each other out)
now since the 3.14 is being multiplied on this side, we must divide by 3.14 on both sides to get rid of it.
904.8/3.14 = 3.14*h /3.14
h= 208.2 !!
