Detailed Solution
Download Solution PDFसमजा गाडीचा प्रारंभिक वेग (u) आणि अंतिम वेग (v) आहे. तर येथे v = 0 असताना, गाडी थांबते.
गतीविषयक 3 ऱ्या नियमाच्या समीकरणानुसार,
v2 - u2 = 2aS1
0 - u2 = 2aS1
S1 =
जेव्हा प्रारंभिक वेग दुप्पट केला जातो, तेव्हा u = 2u
v2 - u2 = 2aS2
2aS2 = -(2u)2
S2 =
समीकरण (i) आणि समीकरण (ii) वरून
S2 = 4S1
- अशाप्रकारे, गाडी थांबवण्यासाठी तीन पट अधिक अंतर लागेल.तर, गाडी थांबवण्यासाठी ती तिप्पट जास्त अंतर घेते.
