A) 52 m
B) Zero
C) 16m
D) \[2\sqrt{2}m\]
E) \[4\sqrt{2}m\]
Correct Answer: D
Solution :
Displacement is distance from initial to final position. In \[40\text{ }s1\] round In \[3\times 60=180\text{ }s4\frac{1}{2}\]round Displacement for 4 rounds is zero. For\[\frac{l}{2}\]round, length of diagonal\[=2\sqrt{2}m\].You need to login to perform this action.
