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.

-1.5 m/s
-1.5 m/s
1.5 m/s
1.5 m/s
-1.6 m/s
-1.6 m/s
1.6 m/s
-1.1 m/s²
To find the acceleration, you would use the formula: acceleration = change in velocity / time taken
The change in velocity is 13 m/s - 5.5 m/s = 7.5 m/s
The time taken is 5 seconds
So, acceleration = 7.5 m/s / 5 s = 1.5 m/s²
The correct answer is 1.5 m/s²
