If the distance `s` travelled by a particle in time `t` is `s=a sin t +b cos 2t`, then the acceleration at `t=0` 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 distance s travelled by a body in time t is given by s = a/t + bt^2 then the acceleration equals

The distance s feet travelled by a particle in time t seconds is given by s=t^3-6t^2-4t-8 . It's acceleration vanishes at time t =

The distance s feet travelled by a particle in time t second is given by s = t^3 - 6t^2 - 4t -8 . It acceleration vanishes at time t =

If s=2t^(3)-6t^(2)+a t+5 is the distance travelled by a particle at time t and if the velocity is -3 when its acceleration is zero, then the value of a is
