The acceleration of a particle starting from rest varies with time according to relation, . Find the velocity of the particle at time instant t.
The displacement of particle is zero at t=0 and at t=t it is x. It starts moving in the x direction with velocity, which varies as , where k is constant. The velocity-
1. varies with time
2. is independent to time
3. inversely proportional to time
4. inversely proportional to acceleration
