Refer to Add Math 360 Text Page 499 Activity 20A
for detailed instructions.
1. At what time t does the particle change direction (turn back)?
2. When is the particle instantaneously at rest? (State the value of t when this occurs)
3. Is the velocity of the particle at time t = 0 , also zero? If not, what is the velocity?
4. When does the particle return to the fixed point O?
