If `S=6t^(2)-t^(3)`, then the body comes to rest after time `t=`

If S=9t-(t^(3))/(3) , the particle to rest after time t=

The displacement x of a body varies with time t as x= -2/3 t^(2)+16 t+2 . The body will come to rest after :

A particle is moving in a striaght line according as S=15t+6t^2-t^3 , then the time it will come to rest is

A particle is moving in a striaght line according as S=15t+6t^2-t^3 , then the time it will come to rest is

If a particle moves according to the law s=6t^(2)-(t^(3))/(2) , then the time at which it is momentarily at rest is

If a particle moves according to the law s=6t^(2)-(t^(3))/(2) , then the time at which it is momentarily at rest is

A particle starts from rest with a time varying acceleration a=(2t-4) . Here t is in second and a in m//s^(2) Particle comes to rest after a time t= ………… second
