A particle is moving in a plane with velocity given by:
\(\vec{v}=\hat{i}\left(u_{n}\right)+\hat{j}(\mathrm{am} \cos \omega t)\)
if the particle is at the origin at t = 0:
Then, distance of the particle after \(t=\frac{3 \pi}{2 \omega}\) from the origin is
- \(\sqrt{\left(\frac{u_{a} \pi}{\omega}\right)^{2}+a^{2}}\)
- \(\sqrt{\left(\frac{u_{0} 3 \pi}{\omega}\right)^{2}+\frac{a^{2}}{4}}\)
- \(\sqrt{\left(\frac{u_{n} 3 \pi}{2 \omega}\right)^{2}+a^{2}}\)
- None of these
Answer
(A) ( u_ a )^ 2 +a^ 2
