If a girl is running along straight road with a uniform velocity 1.5 m/s .Find the acceleration

Acceleration = 0

Explanation:

Uniform Velocity = 1.5m/s

Acceleration is defined as the change in Velocity of a moving object with time.

Acceleration = (V2 - V1) / t

Where v2 and V1 are velocities and t is time

A body is said to be moving at a uniform Velocity if the Velocity with which it moves is constant. That is there is no change in the Velocity as the body progresses

Mathematically ;

(V2 - V1) = 0 [uniform / constant Velocity]

acceleration = 0 / time

Acceleration = 0
