A store had 40 cases of pop on hand at the beginning of the week and bought 120 cases from the vendor during the weed and had 63 cases on hand at the end of the week How many cases did the store sell for the week ?

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.

b. x- 48 =120
