The displacement is given by `x = 2t^(2) +t +5`, the acceleration at `t = 2s` is

The displacement is given by x = 2t^(2) + t + 5 , the acceleration at t = 5 sec will be-

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

The displacement of a particle is described by x = t + 2t^(2) +3t^(3) -4t^(4) The acceleration at t = 3s is

If displacement x at time t is x = sqrt(1+ t^(2)) , then acceleration is

If displacement x at time t is x=sqrt(1+t^(2)) , then acceleration is

The displacement of a body is given by x = 2t^(3) - 6t^(2) + 12t + 6 . The acceleration of body is zero at time ti is equal to :

If displacement S at time t is S=t^(3)-3t^(2)-15t+12 , then acceleration at time t=1 sec is
