An object is initially travelling at 4.0 m/s towards the left. If it is then accelerated for 1.9 s and its final velocity is 6.0 m/s towards the right, what is its average acceleration?
To find the average acceleration, we can use the formula:
average acceleration = (final velocity - initial velocity) / time
Initial velocity = -4.0 m/s (since it is moving towards the left)
Final velocity = 6.0 m/s (since it is moving towards the right)
Time = 1.9 s
average acceleration = (6.0 m/s - (-4.0 m/s)) / 1.9 s
average acceleration = (6.0 m/s + 4.0 m/s) / 1.9 s
average acceleration = 10.0 m/s / 1.9 s
average acceleration = 5.26 m/s^2
Therefore, the average acceleration of the object is 5.26 m/s^2.
