the distance that a spring will stretch varies directly as the force applied to the spring. A force of 12 pounds is needed to st

vodka [1.7K]

Answer:

Force required, F = 20 pounds

Step-by-step explanation:

We have given,

force needed to stretch a spring , F = 12 pounds

Stretched length, x = 9 inches

Since, spring force formula can be given as: F = kx

i.e 12 = k · 9

or k = $\frac{12}{9}$ = 4/3

Now we need to find force for the stretch length = 15 inches

i.e F = kx , here x =15inches , k = 4/3 and F= ?

or F = (4/3) · 15

or F = 20 pounds

Hence force required, F= 20 pounds
