average accelrtation = change in velocity/change in time
= (65-47)m/s/(12-3)s
= 2 m/s^2
seconds squared, not to the fourth
The velocity of an object is +47 meters per second at 3.0 seconds and is +65 meters per second at 12.0 seconds. The average acceleration of the object is 2.0 m/s to the fourth power
