Jennifer swims 4 complete lengths of a 50m pool.

What distance did she swim?
What is her displacement?

d = 4 * 50 = 200 m.

Disp. = 0, The distance from starting point.

To find the distance Jennifer swam, we need to multiply the number of lengths she swam by the length of the pool. Each length is 50 meters, and Jennifer swam 4 complete lengths.

Distance = Length of pool x Number of lengths
Distance = 50m x 4
Distance = 200m

Therefore, Jennifer swam a distance of 200 meters.

Now, let's calculate Jennifer's displacement. Displacement is a vector quantity that measures the change in position from the starting point to the ending point. In this case, since Jennifer started and ended at the same point, her displacement will be zero. Displacement does not take into account the total distance covered; it only considers the change in position.

Therefore, Jennifer's displacement is 0 meters.
