The acceleration of a particle is increasing linearly with time t as bt. The particle starts from origin with initial velocity u. The distance travelled by the particle in time t will be:...
Sorry, I've made a mistake. We have, aceeleration, a = bt Integrating on both sides, At t = 0, v = u. So, c = u Integrating both sides : At t = 0 the particle was at origin, so c = 0 Hence, ...
