Agroup of fitness club members lose a combined total of 28 kilograms in 1 week. there are approximately 2.2 pounds in 1 kilogram. assuming the weight loss happened at a constant rate, about how many pounds did the group lose each day?

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.
