Question
Student C's highest speed is 2 m/s towards the motion detector.
Student A is always farther away from the detector than student B.
Student B and C are always next to each other.
Student C's highest speed is 1 m/s towards the motion detector.
(b) Which of the following correctly describes the situation at time t = 4 s ?
Student C is moving at a slower speed than student B.
Student A is farther away from the detector than student C.
Student A is closer to the detector than student B.
Student B is moving at a slower speed than student A.
Explanation / Answer
a] Third option is correct, B and C are always next to each other
Velocity time Graph of B matches with slope position time of graph .of C
b] Student A is closer to detector than B, So third option is correct.
Position of A is 2m, while position of B and C are 4 m each
