A Certain Coiled Wire With Uneven Windings Has The Property That To Stretch It An Amount S From Its Relaxed Length Requi 1 (200.78 KiB) Viewed 36 times

A certain coiled wire with uneven windings has the property that to stretch it an amount s from its relaxed length requires a force that is given by F =bss, so its behavior is different from a normal spring. You suspend this device vertically, and its unstretched length is 22.0 cm. You hang a mass of 18.0 grams from the device, and you observe that the length is now 24.2 cm. What is b? (Start your analysis from the Momentum Principle.) Submit Answer) Tries 0/8 You hold the 18.0 gram mass and throw it downward, releasing it when the length of the spring-like device is 27.9 cm and the speed of the mass is 4.10 m/s. One millisecond later, what is the approximate change in the speed of the mass? Submit Answer) Tries 0/8 At this same time, one millisecond after throwing, what is the approximate change in the stretch of the device? Submit Answer) Tries 0/8
