Answer:

acceleration=change in distance÷change in time

Explanation:

Acceleration=change in distance ÷change in time

A=12÷2.5

A=4.8 m/sec

AL2006

Acceleration (magnitude) = (change in speed) / (time for the change)

Change in speed = (end speed) - (start speed)

Change in speed = (12 m/s) - (7 m/s)

Change in speed = 5 m/s

Acceleration = (5 m/s) / (2.5 s)

Acceleration = 2 m/s²
