Question

A car covers a semicircular track of radius 5 m with a constant speed of π m/s. Find the magnitude of

displacement and average velocity​

Answer 1

Explanation:

Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both. ... Any of these would be considered an acceleration since they change velocity.
