Answer 1

Answer:

(1)yes

(2)yes

(3)no

(4)50m/s

(5)100m/s

Answer 2

Answer:

Explanation:

(i) Yes, both the bodies AandB start from the same position, the origin.

(ii) As distance time graph for both AandB is straight line, therefore, both move with uniform speed.

(iii) No, speed is uniform and acc. =0.

(iv) speed of A =distancetime=50m15s=3.3m/s

(v) speed of B =distancetime=100m10s=10m/s

(vi) Yes, from the slopes of graph, we infer that body B is moving faster than body A.
