Calculating Velocity of a Moving Object

Explanation:

Initial Velocity: When a body starts from rest, its initial velocity is 0 m/s. In this case, the body starts from rest, so the initial velocity (u) is 0 m/s.

Acceleration: The body travels with uniform acceleration of 2 m/s². Uniform acceleration means that the acceleration remains constant throughout the motion of the body.

Displacement: The body makes a displacement of 9m. Displacement is a vector quantity that indicates the change in position of an object. It is measured in a straight line from the initial position to the final position of the object.

Using the equation of motion v² = u² + 2as, we can calculate the final velocity (v) of the body. By substituting the values of initial velocity, acceleration, and displacement into the equation, we find that the velocity of the body after making a displacement of 9m is 6 m/s.
