1. At what time t does the particle change direction (turn back)? 2. During which period of time is the velocity (ds/dt) positive, and in which period of time is the velocity negative? 3. When is the particle instantaneously at rest? (State the value of t when this occurs) 4. Is the velocity of the particle at time t = 0 , also zero? If not, what is the velocity? 5. When does the particle return to the fixed point O?
