A bridge contactor was hired to replace a truss bridge in a local town. The bridge needed to have 6 square sections replaced. When asked how much steel was
needed for one section he said, “24 linear metres”. What were the dimensions of
each section? Did he really need 24 linear metres of steel per section?

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.
