<span>The equation of motion for a rocket in vertical flight can be obtained from newton’s second law of motion and is constant-mass system. The equation of motion for a body mass varies with time and mass. When force acts on rocket, the rocket will accelerate in the direction of force. Therefore, force is equal to the change in momentum per change in time. For constant mass, force equals mass times acceleration.</span>

suppose you increase your walking speed from 5m/s to 14m/s in a period of 1 . what is your acceleration?
Ne4ueva [31]

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

change in speed = (ending speed) - (starting speed)  =  9 m/s.

Acceleration  =  (9 m/s) / (period of 1) .

We don't know the units of the 'period of 1'.
If it means '1 second', then the acceleration is   9 m/s² .
