<h2><u>
Answer</u>
:</h2>
Distance = 50m
Displacement = 50m to the right
<h2><u>
Explanation</u>
:</h2>
<em>Distance</em> is the total length of a given path. It is a scalar quantity and thus takes no consideration on the direction of the path.
<em>Displacement</em> on the other hand is the change in position of an object. It is a vector quantity and takes consideration on the direction of the object.
From the question:
<em>The swimmer swims half lap by moving from the left end to the right end of a pool that is 50m long.</em>
Distance = total length of the given path = 50m
Displacement = change in position of the swimmer from the left end (0m) to the right end (50m) = 50 - 0 = 50m
Since direction is important in displacement, the complete details of the displacement should be 50m to the right
