APFIVE Kinematics from a Position Function
Two different representations of the same motion are given: (1) a position function x(t) = 5t² - 2t³ and (2) a velocity-time graph showing v = 0 at t = 0 and t = 5/3. What can be concluded about the object’s motion?
A
The object reverses direction at t = 5/3 s
B
The object experiences constant acceleration
C
The object’s acceleration is zero at t = 5/3 s
D
The object reaches maximum displacement at t = 5/3 s
