The displacement of a particle in time 't' is given by S = t^(3) - t^(2) - 8t =18 . The acceleration of the particle when its velocity vanishes is

The displacement s of a moving particle at a time t is given by s=5+20t-2t^(2) . Find its acceleration when the velocity is zero.

The distance s of a particle in time t is given by s=t^3-6t^2-4t-8 . Its acceleration vanishes at t=

The distance s moved by a particle in time t is given by s=t^(3)-6t^(2)+6t+8 . When the acceleration is zero, the velocity is ………..

The displacement of a particle at time t is given by s= 2t^(3) -5t^(2)+ 4t-3 . The time when the acceleration is 14ft/ sec^(2) is

If the distance S travelled by a particle in time t is given by s = t^(2) - 2t + 5 then its acceleration is

If the distance s travelled by a particle in time t is given by s=t^2-2t+5 , then its acceleration is

If the displacement in time t of a particle is given by s = ae^(t) + be^(-t) . Then the acceleration is equal to
