Displacement `s` of a particle at time `t` is expressed as `s=1/2t^3-6tdot` Find the acceleration at the time when the velocity vanishes (i.e., velocity tends to zero).

If s=(1)/(2)t^(3)-6t , then the find the acceleration at time when the velocity tends to zero.

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 displacement s of a particle at a time t is given bys =t^(3)-4t^(2)-5t. Find its velocity and acceleration at t=2 .

The displacement 's' of a moving particle at a time H is given by s=5+20t-2t^(2) .Calculate its acceleration when the velocity is zero.

If S=t^(3)-64t-8 , then acceleration vanishes at time t=

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

5.The displacement s of a particle at a time t is given by s=2t-5t+4t-3, find (i) the time when the acceleration is 14 ft/sec (ii) the velocity and the displacement at that time.

If displacement of particle is s=(t^(3))/(3)-(t^(2))/(2)-(t)/(2)+6 , then acceleration of the particle when its velocity is (3)/(2) , is

The displacement of a particle in time t is given by s=2t^2-3t+1 . The acceleration is
