A cream tangerine is thrown directly upward past three evenly spaced windows of equal heights. Rank the windows according to (a) the average speed of the cream tangerine while passing them, (b) the time the cream tangerine takes to pass them, (c) the magnitude of the acceleration of the cream tangerine while passing them, and (d) the change in velocity in the speed of the cream tangerine during the passage, greatest first.

(a) 123 - The item slows as it goes up

(b) 321 - A slower speed = longer time to pass

(c) They are all equal if the item is thrown (accelerated upward) below window 1 after that they are all experiencing 1G of acceleration back down to earth.  To throw something up you need to overcome the acceleration of gravity 32FPS*S.  Eventually, The acceleration of gravity will win unless this is some sort of moon shot.

(d) 321 the only acceleration on the item is gravity (negative upward acceleration) since the longest time is 3 it experiences the greatest change in velocity

a cream tangerine sounds yummie ! Better catch it, though, before it goes "splodge"  on the return journey to earth.
