An object starts from rest at the origin and moves along the x-axis with a constant
acceleration of 4m/s^2. Its average velocity as it goes from x=2m to x=8m is?
Homework Equations
I think V=bt^2. But not quite sure.
The Attempt at a Solution
No idea, how to solve.
Average velocity is the measure of an object's displacement over a period of time. It is calculated by dividing the total displacement by the total time taken.
While average velocity takes into account the direction of an object's motion, average speed only considers the magnitude of its motion. Average velocity is a vector quantity, while average speed is a scalar quantity.
To calculate average velocity, you need to know the total displacement and the total time taken. The formula for average velocity is: average velocity = total displacement / total time taken.
The unit of measurement for average velocity is meters per second (m/s) in the International System of Units (SI). However, it can also be expressed in other units such as kilometers per hour (km/h) or feet per second (ft/s).
Yes, average velocity can be negative if the object is moving in the opposite direction of its positive axis. This indicates that the object is moving towards its starting point, or in the opposite direction of its initial velocity.
