A) 5, 10
B) 3, 2
C) 4, 2
D) 3, 4
Correct Answer: A
Solution :
Displacement equation \[x=3\,\sin \,2t+4\,\cos \,2t\] Comparing this equation with \[x={{a}_{1}}\,\sin \omega t+{{a}_{2}}\,\cos \,\omega t\] \[{{a}_{1}}=3,\,{{a}_{2}}=4,\,\omega =2\] \[a=\sqrt{{{a}_{1}}^{2}+{{a}_{2}}^{2}}\] \[=\sqrt{{{3}^{2}}+{{4}^{2}}}=5\] \[{{\upsilon }_{\max }}=a\omega =5\times 2=10\]You need to login to perform this action.
