Use the graph to calculate the acceleration of the rocket while the engine is working. Show all steps.

The acceleration of the rocket while the engine is working is 5 meters per square seconds.

Explanation:

Since the rocket accelerates uniformly, the velocity increases linearly and the acceleration (), measured in meters per second, can be determined by definition of secant line:

(1)

Where:

, - Initial and final instants, measured in seconds.

, - Initial and final velocities, measured in meters per second.

If we know that , , and , then the acceleration of the rocket while the engine is working:

The acceleration of the rocket while the engine is working is 5 meters per square seconds.
