a) When is the particle at rest?

b) During what time interval is the particle moving right? Left?

c) At what time is the acceleration zero? What is the velocity at this time?

A particle is moving along the x-axis so that its position at any time, t > 0, can be found by the function:
X(t) = t3 – 15t2 + 48t
Transcribed Image Text:A particle is moving along the x-axis so that its position at any time, t > 0, can be found by the function: X(t) = t3 – 15t2 + 48t
