A particle is constrained to move at a constant speed on an inclined plane (ABCD) along the curved path shown in the figure. Edges AD and BC are parallel to the y axis. The inclined plane makes an angle 𝜃 with the 𝑥𝑦-plane. The velocity vector of the particle makes an angle 𝜙 with the dotted line which is parallel to edge AB. If the speed of the particle is 2 m/s, 𝜙ൌ30°, and 𝜃ൌ40°, then the 𝑧-component of the velocity of the particle in m/s is __________
- A. െ1.32
- B. െ1.00
- C. െ1.11
- D. െ1.50
Answer: C. െ1.11
