Question

3. Assume that the elastic bands on a slingshot work like a spring with a

spring constant of 250 N/m. If you have to pull back with 100 N of stretch
(spring) force to fully stretch the bands, how far will the elastic bands stretch?

Please help me

Answer 1

0.6

Step-by-step explanation:

I got it right

Answer 2

As you stretch the band a distance x, the force you need to exert has a magnitude of (250 N/m) x.

So if 100 N is required to stretch it to maximum length, then this length is x such that

100 N = (250 N/m) x ==> x = (100 N)/(250 N/m) = 0.4 m
