If the displacement of a particle is `x=t^(3)-4t^(2)-5t`, then the velocity of particle at t=2 is

If the displacement of a particle is x=t^(3)-4t^(2)-5t , then the acceleration of particle at t=2 is

If displacement of particle is s=t^(3)-6t^(2)+9t+15, then velocity of the particle at beginning is

If the displacement of a particle is given by s=2t^(3)-5t^(2)+4t-3 , then its velocity when acceleration is 14" ft/sec"^(2) , is

If displacement of particle is s=(t^(3))/(3)-(t^(2))/(2)-(t)/(2)+6 , then velocity of the particle at t=4 sec. is

If displacement of particle is x=160t-16t^(2) , then at t=1and t=9, velocities are

If S=t^(4)-5t^(2)+8t-3 , then initial velocity of the particle is

The rate of change of displacement with respect to time is known as velocity.If displacement of a particle is s=3t^(2)+4t+5 then velocity as a function of time

The displacement of a particle at time t is x, where x=t^4-kt^3 . IF the velocity of the particle at time t=2 is minimum, then

The displacement of a particle at time t is x, where x=t^4-kt^3 . IF the velocity of the particle at time t=2 is minimum, then

If the displacement of a particle is given by s=2t^(3)-5t^(2)+4t-3 , then its displacement when acceleration is 14" ft/sec"^(2) , is
