A specially trained mouse runs counterclockwise in a circle of radius 0.6 m on the floor of an elevator with speed 0.3 m/s, while the elevator ascends from ground level (along the z-axis) at a speed of 12 m/s. Find the mouse’s acceleration vector as a function of time. Assume that the circle is centered at the origin of the xy-plane and the mouse is at (2, 0, 0) at t = 0.
