Answer:

(a) during 2 to 5 seconds and 7 to 9 seconds

(b) during 5 to 7 seconds

Explanation:

(c) The obj is moving at greater speed during the time 7 to 9 sec.

This is because:

Speed during CD = 400m/2s = 200m/s

Speed of BC = 0/2 = 0m/s

Speed of AB = 300m/3s = 100m/s

Since the speed during 7 to 9 sec is more
