Dave and his sister picked out two pumpkins at the pumpkin patch. the pumpkins cost $0.47 per pound. david's pumpkin weighed 13.24 pounds and his sister's weighed 10.6 pounds. how much did they pay for both pumpkins?

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.

answer: idk
