Question: The rectangular coordinates of a particle are given in millimeters as functions of time t in seconds by x = 30 cos 2t, y =

The rectangular coordinates of a particle are given in millimeters as functions of time t in seconds by x = 30 cos 2t, y = 40 sin 2t, and z = 20t + 3t². Determine the angle θ₁ between the position vector r and the velocity v and the angle θ₂ between the position vector r and the acceleration a, both at time t = 2 s.
