Question
Download Solution PDFएक वस्तु विराम अवस्था x = 0 मीटर और t = 0 s से शुरू होती है। यह x-अक्ष के साथ 2m/s2 के निरंतर त्वरण के साथ चलता है। 1 s और 5 s के बीच इसका औसत वेग क्या है?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFअवधारणा:
- औसत वेग = कुल विस्थापन / कुल समय अवधि
- गति का समीकरण:
- v = u + at
- v2 = u2 + 2as
- s = ut + 1/2 at2
गणना:
दिया गया है:
समय अंतराल = 5 s और 1 s, प्रारंभिक वेग u = 0, और, त्वरण a = 2 m/s2
जब कोई वस्तु विरामवस्था से शुरू होती है, तो 1 सेकंड और 5 सेकंड में तय की गई कुल दूरी है,
s = ut + 1/2 at2
वस्तु विरामावस्था में है, इसलिए, u = 0 m/s.
\(s_2 - s_1 = \frac12 a(t_2^2-t_1^2)\)
\(s_2 - s_1 = \frac12 \times 2(5^2-1^2)\)
s2 - s1 = 24 m
लिया गया कुल समय, t = t2 - t1 = 5 - 1 = 4 सेकंड
औसत वेग = कुल विस्थापन / कुल समय अवधि
औसत वेग = 24/4 = 6 m/s
समय 1 s और 5 s के बीच औसत वेग = 6 m/s
