A horse is galloping at 13 m/s. Five seconds later after running uphill, the horse is moving at 5.5 m/s. Find the acceleration that describes this change in velocity.
Responses
-1.5 m/s
1.5 m/s
-1.6 m/s
1.6 m/s
-1.5 m/s.
To find the acceleration, we can use the equation:
acceleration = (final velocity - initial velocity) / time
acceleration = (5.5 m/s - 13 m/s) / 5 s
acceleration = -7.5 m/s / 5 s
acceleration = -1.5 m/s
Therefore, the acceleration that describes the change in velocity is -1.5 m/s.
