Solution
Solution Steps
Step 1: Analyze the motion from A to B
The object moves from 0 meters to 6 meters in 4 seconds. This represents a positive velocity.
Step 2: Analyze the motion from B to C
The object stays at 6 meters from time = 4 seconds to time = 11 seconds. The object is at rest during this period.
Step 3: Analyze the motion from C to D
The object moves from 6 meters to 8 meters from time = 11 seconds to time = 12 seconds. This represents a positive velocity.
Final Answer
The object moves with constant velocity from A to B. It moves with zero velocity from B to C. It moves with constant velocity from C to D.
