Answer:
I think it is a or c hope this helps
As we know,
so, let's solve for velocity (v)
Answer:
a) Mat swum 100 meters.
b)after 4 length , Mat's displacement is zero.
Explanation:
As given, Mat and David are training for the swimming team , and Length of 1 side of the pool is 25 meter.
As swimming pool will be a cube or a cuboid , so it has only 4 sides.
a)
1 length = 23 meter
⇒4 length = 4×25 = 100 meter
So, Mat swam 100 meters.
b)
As after swam 4 lengths of the pool, Mat reaches to its initial position i.e Mat come back to its starting point.
As Displacement is always measures from the starting point.
So, after 4 length , Mat's displacement is zero.
