A) \[{{S}_{2}}\]and \[{{S}_{3}}\]
B) \[{{S}_{1}}\]and \[{{S}_{4}}\]
C) \[{{S}_{1}},\text{ }{{S}_{3}}\]and \[{{S}_{4}}\]
D) All four statements
Correct Answer: C
Solution :
(i) Average velocity \[=\frac{Displacement}{Time\text{ }taken}\] \[{{\vec{v}}_{Av}}=\frac{\Delta r}{\Delta t}\] (ii) As we know for a given time interval Distance \[\ge \]\[\left| Displacement \right|\] Average speed \[\ge \]\[\left| ~Average\text{ }velocity \right|\] (iii) A body moving in a given direction with non-zero velocity cannot have zero speed. (iv) In general average speed is not equal to magnitude of average velocity.You need to login to perform this action.
