as a guest was sneaking away, the groundskeeper was 4 feet (48 inches) away and pushed an 84 inches ladder onto the suspect. They very top of the ladder hit the guest on the top of the head. Find the height of the guest in inches, then convert in feet. His weight is 207

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.
