A particle moves in a strainght line with uniform acceleration . Its velocity at time t=0 is `v_1` and at time `t_2=t` is `v_2.` The average velocity of the particle in this time interval is `(v_1+v_2)//2` Is this correct? Substantiate your answer.

Text Solution

Verified by Experts

`t_1=0impliesu=v_1`
`t_2=timpliesv=v_2`
Average velocity `=(u+v)/2`
`=(v_1+v_2)/2`
