Sagot :
Answer:
When a velocity is changing as a result of a constant acceleration, the average velocity can be found by adding the initial and final velocities, and dividing by 2. The unit for velocity is meters per second (m/s). Note that this formula applies for constant acceleration only
Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two.
Average speed = Distance / time elapsed = 180 meters / 6 seconds = 30 meters/second. Average velocity = Displacement / time elapsed = 60 meters / 6 seconds = 10 meters/second.
