Applied Calculus: position vector r(t)=12√ti + t^3/2 j

[tyrahanani]

Help me to solve this problem. Because i tried to find it's hard. hopefully you can help.

Suppose that the position vector of a particle moving in a plane is
r(t)=12√ti + t^3/2 j

Find the minimum speed of the particle and its location when it has this speed.

How the co-ordinates of a particle and the position vector of that particle, are related?

How the speed of a particle and the position vector of that particle, is related?
