Camilla makes and sells jewelry. She has 8.160 silver beads and 2,880 black beads
to make necklaces. Each necklace will contain 85 silver beads and 30 black beads.
How many necklaces can she make?

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.
