t=0 velocity=0
differentiate the given equation to get the velocity

Balajirv: how did u find dv/dt=2.5

pratik6555: yes my mistake. in the hurry i forgot to multiply 2 . u r correct

pratik6555: and it is dx/dt= velocity. wat u have written is dv/dt which is acceleration (not asked in the question)

Balajirv: i will post it again can u explain in stes

Balajirv: i will post it again can u re explain

Balajirv: with steps
