The position vector of a point is given by, r=(4/3t^3-2t)i+t^2j. Find the velocity and acceleration of the point at t=3sec. [The distance is measured in meters]

Here the position vector of the point is given by,   So the velocity is  Now, at t=3sec. So the magnitude of the velocity is, Again we know that acceleration…
