The rectangular coordinates of a particle are given in millimeters as functions of time t in seconds
Question:
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.
