Inicial acceleration of a particle moving in a straight line is a0 and inicial velocity is zero. The acceleration reduses continuesly to half in every t0 seconds as a = a0 / 2(t/t0). Find terminal velocity of the particle .

what is the expression??/
well whatever it may be.....
write a = dv/dt
& then integrate it.....
u will surely get the answer...

im not getting d ans. wat does terminal vel actually means?
a = 1/2t (a, t, ) hope u got the expression...

terminal velocity is the final velocity of the body, even when the acceleration is acting on it , at t = infinity.
here your acceleration is an exponential expression..
a = a0e-kt
here k is equal to ln2/t0
now put a = dv/dt
integrate from limits a0 to a, and t = 0 to infinity.

I am getting the answer probably it is
a0.t0 / 2 Ans

Dear
you wrote a = a0 / 2(t/t0) since the object is starting from rest so at t= 0 the acceleration becomes infinite which is not physically possible .

IT IS THE FINAL VELOCITY OF ANY MOVING BODY. USE FORMULA OF VELOCITY=DISTANCE/TIME.
