Answer 1

Answer:

Explanation:

Initial velocity= 25 m/s

final velocity= 10 m/s

time taken= 3 seconds

Acceleration (in this case, deceleration)= final velocity-initial velocity/time

= 10-25/3 = -15/3 = -5 m/s²

Answer 2

Answer:

Explanation:

Initial velocity= 25 m/s

final velocity= 10 m/s

time taken= 3 seconds

Acceleration (in this case, deceleration)= final velocity-initial velocity/time

= 10-25/3 = -15/3 = -5 m/s²
