Instead of the one-fold speed [[$ v $]]​, we will substitute the two-fold speed [[$ 2v $]]​.<br/> ​[[$$ s=\frac{1}{2F_{\text{kitka}}}m(2v)^2=\frac{1}{2F_{\text{kitka}}}m\cdot 4v^2= 4\cdot\frac{1}{2F_{\text{kitka}}}mv^2 $$]]​<br/> Therefore the braking distance is quadrupled as speed is doubled. 2017-12-26T17:49:38+02:00 https://peda.net/id/6215635cea5 2017-12-26T17:49:38+02:00 <dl><dt><!--filtered attribute: class="thumbnail"--><a href="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mkj/img_1740-png#top" title="IMG_1740.PNG"><img src="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mkj/img_1740-png:file/thumbnail/b65a788b6fb7a96646ea8bc2baa5fc01cca12427/IMG_1740.PNG" alt="" title="Työohje" class="thumbnail" loading="lazy"/></a></dt> <dd>Työohje</dd> <dt><!--filtered attribute: class="thumbnail"--><a href="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mkj/img_1741-png#top" title="IMG_1741.PNG"><img src="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mkj/img_1741-png:file/thumbnail/235aa254f3b542758302e9f33a941bdcd5295262/IMG_1741.PNG" alt="" title="Raporttipohja" class="thumbnail" loading="lazy"/></a></dt> <dd>Raporttipohja</dd> <dt><!--filtered attribute: class="thumbnail"--><a href="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mkj/img_1742-png#top" title="IMG_1742.PNG"><img src="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mkj/img_1742-png:file/thumbnail/560ce90cc49495ca0c40507f9fee6f0e45fc01c5/IMG_1742.PNG" alt="" title="Raporttiesimerkki" class="thumbnail" loading="lazy"/></a></dt> <dd>Raporttiesimerkki</dd> </dl> 2017-12-26T17:49:38+02:00 https://peda.net/id/6218ec02ea5 2017-07-29T11:11:53+03:00 <span class="center medium"><a href="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mevo/img_1738-png#top" title="IMG_1738.PNG"><img src="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mevo/img_1738-png:file/photo/22a1e3b029c0354c3f94fe7cf51d1f324dfdc869/IMG_1738.PNG" alt="" title="IMG_1738.PNG" class="inline" loading="lazy"/></a></span><span class="center medium"><a href="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mevo/img_1739-png#top" title="IMG_1739.PNG"><img src="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mevo/img_1739-png:file/photo/c13e3b00a58d8bc57c0fdb1291eb7dbf4a2f1979/IMG_1739.PNG" alt="" title="IMG_1739.PNG" class="inline" loading="lazy"/></a></span><span class="center medium"><a href="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mevo/img_1743-png#top" title="IMG_1743.PNG"><img src="https://peda.net/p/janne.rytkonen/yf2/liike-8/energia/ty%C3%B6/mevo/img_1743-png:file/photo/b8612d8a7e09e714b2bddbdec37475972d23eea9/IMG_1743.PNG" alt="" title="IMG_1743.PNG" class="inline" loading="lazy"/></a></span> 2017-12-26T17:49:38+02:00
