Answer:

Step-by-step explanation:
We are given that velocity vector of a particle

When t=0 then the particle is at the point (0,-1,1).
We have to find the position of particle at time t.
We know that
Velocity =
Therefore,

Integrate on both sides then we get


Substitute the value of point at time t=0 then we get
C=
Substitute the value of C then we get

Therefore, the position of particle at time t
