5. A journalism teacher wants to determine
whether his students would prefer to attend a
national writing convention or tour of a local
newspaper press. The journalism teacher has
a total of 120 students in 4 different classes.
What would be a representative sample in this
situation?

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.
