A train moves east at 20 m/s and a passenger walks toward the front at 2.0 m/s relative to the train. The passenger's velocity relative to the ground is
A.22 m/s east
B.18 m/s east
C.22 m/s west
D.2.0 m/s east
Explanation
Core Concept
Velocities in the same direction add: 20 + 2.0 = 22 m/s east.
Correct Answer
A22 m/s east
