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
