The displacement of a particle starting from rest (at \ell = 0 ) is given by \(5 \quad 6r^{i} - r^{2}\) . The time in seconds at which the particle will attain zero velocity again, is
Text Solution
Verified by ExpertsThe correct answer is:
B
\(v - \frac{ds}{dt} - 12t + 3t^{2}\)
Velocity is zero for \ell = 0 and \(t = 4 \text{ sec}\)
