The displacement of the cyclist from point A to B is 39.3 m.
Displacement of the cyclist
The displacement of the cyclist is equal to the change between the final position and initial position of the cyclist. This can also be described as the shortest distance between two positions.
From the given image, the displacement of the cyclist from point A to B can be determined by formula for calculating length of arc,
D = (θ/360) x 2πr
D = (90/360) x 2π x 25
D = 39.3 m
Thus, the displacement of the cyclist from point A to B is 39.3 m.
