<span>When still rolling your bike had kinetic energy, or energy in the form of motion. The forces resisting this motion--a mixture of many factors including air resistance, tire friction, friction in the hubs of the wheels, etc...--eventually decrease the kinetic energy of the bike to zero as it reaches a complete stop.</span>
Answer:
3.14 m/s
Explanation:
We are given that
Mass of object=1.1 Kg
Spring constant=160 N/m
a.We have to find the amount by which the spring is stretched from its unstrained length(it means x)
We know that F=kx ,![g=9.8m/s^2](https://tex.z-dn.net/?f=g%3D9.8m%2Fs%5E2)
![x=\frac{F}{k}=\frac{1.1\cdot 9.8}{160}=0.0674 m](https://tex.z-dn.net/?f=x%3D%5Cfrac%7BF%7D%7Bk%7D%3D%5Cfrac%7B1.1%5Ccdot%209.8%7D%7B160%7D%3D0.0674%20m)
![x=0.0674\times 100=6.74 cm (1m=100 cm)](https://tex.z-dn.net/?f=x%3D0.0674%5Ctimes%20100%3D6.74%20cm%20%281m%3D100%20cm%29)
b.When an object is pulled straight down by an additional distance 0.26 m and released from rest.
x=0.26 m
We have to find the speed with which the object passes through its original position on the way up.
(Law of conservation of energy)
![\frac{1}{2}mv^2=\frac{1}{2}kx^2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E2%3D%5Cfrac%7B1%7D%7B2%7Dkx%5E2)
Substitute the values then we get
![1.1\cdot v^2=160\cdot (0.26)^2](https://tex.z-dn.net/?f=1.1%5Ccdot%20v%5E2%3D160%5Ccdot%20%280.26%29%5E2)
![v=\sqrt{\frac{160\cdot(0.26)^2}{1.1}}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cfrac%7B160%5Ccdot%280.26%29%5E2%7D%7B1.1%7D%7D)
![v=3.14 m/s](https://tex.z-dn.net/?f=v%3D3.14%20m%2Fs)
Hence, the speed of an object with which the object passes through its original position on the way up=3.14 m/s
Answer: is it .03oz ?
Explanation: I really aren’t sure
An intensive property will not change if you took a piece ( like color or temperature )
<span>An extensive property will change ( like weight or volume) </span>
<span>1) wall: hard ( intensive); yellow (intensive) </span>
<span>2) ice cube: cold( intensive) ; large( extensive) </span>
<span>3) sofa: brown (intensive); long ( extensive) </span>
<span>4) dog: black ( intensive); heavy ( extensive) </span>
<span>5) stove: hot ( intensive); white (intensive) </span>
