Answer:
Answer a:-
As we know
Speed = Distance/Time
Speed of
(A) 5m/s
(B) 3m/s
(C) 2 m/s
Explanation:
In case (A)
Distance = 20m
Time = 4s
Speed = 20/4
= 5m/s
In case (B)
Distance = 18m
Time = 6s
Speed = 18/6
= 3m/s
In case (C)
Distance = 16m
Time = 8s
Speed = 16/8
= 2m/s
Answer b:-
We know that slope of distance- time graph gives speed, here out of the 3 given graphs the first graph has highest slope. So, the speed is highest in first case.
