An object of mass 3 kg is at rest. If a force \(\vec{F}=\left(6 t^{2} \hat{i}+4 t \hat{j}\right)\) N is applied on the object, then the velocity of the object at t = 3 s is:
- \(18 \hat{i}+3 \hat{j}\)
- \(18 \hat{i}+6 \hat{j}\)
- \(3 \hat{i}+18 \hat{j}\)
- \(18 \hat{i}+4 \hat{j}\)
Answer
(B) 18 i +6 j
