**Problem 4:** A 5 lb box is projected with a speed of 20 ft/s at point "A" up a smooth vertical circular track. Determine the angle “θ” when the box leaves the track. **Answer:** The angle at which the box leaves the track, θ₈, is 135.5°. **Diagram Explanation:** The diagram features a smooth vertical circular track with a radius of 3 ft. A box starts at point "A" at the bottom of the circle with an initial velocity represented by an arrow pointing upward along the circular path. The angle θ is measured from the vertical axis to the position where the box leaves the track.
