Three parcels weigh 2 pounds. two parcels weigh the same. the lightest weight is 5/8 pound lighter than the heaviest weight. how much do each of the parcels weigh? a: 1/8, 1/8, 3/4 b: 1/4, 1/4, 3/2 c: 5/8, 5/8, 3/4 d: 7/8, 7/8, 1/4

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
