Assume that the elastic bands on a slingshot work like a spring with a spring constant of 250 N/m (they actually follow a slightly different, though similar, law than springs). If you have to pull back with 100 N of force to hold the pouch against bands that start out 20 cm long, how long (meters) are the bands when stretched?

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
