A cyclist turns a corner with a radius of 50m at a speed of 10m/s. The cyclist's acceleration is 2 m/s².

What is acceleration?

The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is acceleration. The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g. It is a vector quantity whose strength or magnitude is determined by the norm and whose direction correlates with a plumb bob.

a = v²/r

a = (10m/s)² / 50m

a = 2 m/s²
