8. if the acceleration is constant and the starting velocity is zero, what is the relationship between the acceleration of a falling body (a), the time it takes to fall (:3, and its instantaneous velocity when it hits the ground (v)? (Increases, {Z'iecreases1 or Constant) a vs t As acceleration increases, the time to fall: a vs v As acceleration increases, the velocity at impact: v vs 1 As velocity at impact increases, the time to fall
