Question
Download Solution PDFएक पहिया अपनी धुरी के परितः कोणीय त्वरण α = 6t² + 2 के साथ घूम रहा है, जहाँ α rad/s² में और t सेकंड में है। जब t = 0, स्थिति शून्य ली जाती है और तब इसका कोणीय वेग 5 rad/s है। t = 10 s पर कोणीय वेग क्या होगा?

कोणीय त्वरण दिया गया है, \( \alpha = 6t^2 + 2 \)
कोणीय वेग और कोणीय त्वरण के बीच संबंध है:
\( \frac{d\omega}{dt} = \alpha \)
दोनों पक्षों का समाकलन करने पर:
\( \omega = \int (6t^2 + 2) dt \)
\( \omega = 2t^3 + 2t + C \)
t = 0 पर, प्रारंभिक कोणीय वेग \( \omega_0 = 5 \) rad/s है।
समीकरण में प्रतिस्थापित करने पर:
\( 5 = 2(0)^3 + 2(0) + C \Rightarrow C = 5 \)
इस प्रकार, कोणीय वेग के लिए समीकरण है:
\( \omega = 2t^3 + 2t + 5 \)
t = 10 सेकंड पर,
\( \omega = 2(10)^3 + 2(10) + 5 \)
\( \omega = 2(1000) + 20 + 5 \)
\( \omega = 2025~rad/s\)
