Asked by Andrew
an object is initially moving 15.0 m/s. a minute later, it is moving 25.0 m/s in the opposite direction. What is the displacement and acceleration?

change in velocity = final - initial = -25 - 15 = -40
A = change in velocity/time = -40/60 m/s^2
= -2/3 m/s^2
average velocity = (15-25) /2 = - 10/2 = -5 m/s
displacement = average velocity*time = -5*60 = -300 meters
A = change in velocity/time = -40/60 m/s^2
= -2/3 m/s^2
average velocity = (15-25) /2 = - 10/2 = -5 m/s
displacement = average velocity*time = -5*60 = -300 meters
