An object moving along a circular path of radius 49m covers 3 complete rounds in 2min. Find the distance and displacement of the object at the end of 4mins
Answers
Answer:
Distance = 308 m
Displacement = 0 m
Explanation:
From the question :-
An object is moving in a circular path of radius 49 m.
The object can complete 3 rounds in 2 min.
To find: distance and displacement after 4 min.
Solution :-
Length of circular path = circumference of circular path
= 2*π*r
= 2*22/7*49
= 44*7
= 308 m
If the object covers 3 complete rounds in 2 min then it will cover 6 complete rounds in 4 min.
So, distance covered by the object in 4 min. = 308 * 6
= 1848 m
And displacement = 1848/308
= 6 rounds
(The object is returned to its initial position meaning that displacement is 0)
= 0 m
Hence, the distance and the displacement of the object moving in the circular path is 308 m and 0 m respectively.
