    The velocity and acceleration of particle give position vector

    never mind i know what I've don i forgot to differentite the k bit the second time giving acceleration= 4i+10k

    The velocity and acceleration of particle give position vector

    the position vector of the particle is given by s=e^-2ti+sin(2t)j+5t^k calculate its velocity and acceleration at t=0 to get the velocity i differentiated with respect to t and substituted in t=0, giving me velocity=-2i+2j and that's the same as the answer given but I am not sure how to get...
