The ditance time graph of two bodies A a...

The ditance time graph of two bodies `A and B` are shown in Figure. Observer the graph carefully and answer the following questions :
(i) Do both the bodies start from the same position ?
(ii) Do they have uniform speed ?
(c ) Does anybody have acceleration ?
(iv) What is speed of `A`?
(v) What is speed of `B` ?
(vi) Without actual calculation, can you infer which body is travelling faster ?

Text Solution

Verified by Experts

(i) Yes, both the bodies `A and B` start from the same position, the origin.
(ii) As distance time graph for both `A and B` is straight line, therefore, both move with uniform speed.
(iii) No, speed is uniform and acc. `= 0`.
(iv) speed of A `= ("distance")/("time") = (50m)/(15 s) =3.3 m//s`
(v) speed of B `= ("distance")/("time") = (100m)/(10 s) = 10 m//s`
(vi) Yes, from the slopes of graph, we infer that body `B` is moving faster than body `A`.
