Download Solution PDFएक कण विराम अवस्थेपासून सुरू होऊन एका सरळ रेषेत जातो जिच्या गतीचे समीकरण S = 2t3 - t2 - 1 द्वारे दिले जाते. एका सेकंदानंतर कणाचे त्वरण असेल-
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसंकल्पना:
जर s = f(t)
तर, वेळेच्या संदर्भात प्रथम विकलज वेग दर्शवतो
\(v=\frac{ds}{dt}\)
त्वरण याद्वारे दिले जाते
\(a=\left( \frac{{{d}^{2}}S}{d{{t}^{2}}} \right)\)
जेथे s हे विस्थापन आहे
गणना:
दिलेल्याप्रमाणे:
s = 2t3 – t2 - 1 आणि t = 1 सेकंद.
\(\frac{ds}{dt}=6{{t}^{2}}-2t\)
\(\frac{{{d}^{2}}s}{d{{t}^{2}}}=12t-2\)
\({{\left( \frac{{{d}^{2}}s}{d{{t}^{2}}} \right)}_{t=1s}}=12-2=10 \;m/s^2\)
