a scooter goes from a velocity of 6.9 m/s to a velocity of 4.8 m/s in a time of 5.1 seconds. what is the acceleration of the scooter
To calculate the acceleration of the scooter, we will use the formula:
Acceleration (a) = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 6.9 m/s
Final velocity (v) = 4.8 m/s
Time (t) = 5.1 seconds
Substituting these values into the formula:
Acceleration (a) = (4.8 m/s - 6.9 m/s) / 5.1 s
Simplifying:
Acceleration (a) = (-2.1 m/s) / 5.1 s
Dividing:
Acceleration (a) ≈ -0.4118 m/s²
So, the acceleration of the scooter is approximately -0.4118 m/s². The negative sign indicates that the scooter is decelerating (slowing down).
