If s=2t^(3)+3t^(2)+2t+8 then find time at which acceleration is zero.

If s=2t^(3)+3t^(2)+2t+8 then find time at which acceleration is zero.

If s=2t^(3)+3t^(2)+2t+8 then find time at which acceleration is zero.

If S=(t^(3))/(3)-2t^(2)+3t+4 , then

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

The position of a particle moving along a horizontal line of any time t is given by s(t)=3t^(2)-2t-8 . The time at which the particle is at rest is

The position of a particle moving along a horizontal line of any time t is given by s(t)=3t^(2)-2t-8 . The time at which the particle is at rest is …………….. .

If S=2t^(3)-3t^(2)+15t-8 ,then the initial velocity is
