Starting from rest, acceleration of a particle is \(\omega = 2(r - 1).\) The velocity of the particle at \ell = 5x is
Text Solution
Verified by ExpertsThe correct answer is:
A
\(\therefore a - \frac{dv}{dt} - 2(t - 1)\) \(\to d/ \quad 2[t-1] dt\)
\(\Rightarrow v = \int_0^2 (t-1) \, dt = 2 \left| \frac{t^2}{2} - t \right|_0^2\) \(= 2 \left| \frac{25}{2} - 5 \right|\) = 15 m/s
