A:The dissaperance of a solid stirred in water
D) Yes. Even though the initial and final velocities are the same, there is a change in direction for the ball.
Acceleration (a) = change in velocity (v) over time (t), let's consider moving right is (+) and moving left is (-)
a = (vf - vi)/t = (-5 - +5)/t
a = (-10)/t
So even though the number looks the same from vi to vf, there actually is a negative acceleration of 10m/s/s.
