Question

You can calculate acceleration with the following equation:
Acceleration = (final velocity - starting velocity) ÷ time it takes to change velocity

A plane passes over Centerville with a velocity of 9,000 m/s north. Fifty seconds later it passes over Middleton at a velocity of 12,000 m/s north. What is the plane's acceleration from Centerville to Middleton?
60 m/s/s north
40 m/s/s north
240 m/s/s north
120 m/s/s north

Answer 2

Youre actually given everything from the problem. You have the initial velocity (9,000) and the final vel (12,000) and you know that it's time taken is 50 seconds between the velocity change, so then just use your given acceleration formula
