A city skyscraper is 1,450 feet tall. A scale model is made that is 1:290 of its size. How tall is the model?

Height of skyscraper's model = 5 feet

Step-by-step explanation:

Given:

Height of skyscraper = 1,450 feet

Scale model ratio = 1:290

Find:

Height of skyscraper's model.

Computation:

Height of skyscraper's model = Height of skyscraper × Scale model ratio

Height of skyscraper's model = 1,450 × (1/290)

Height of skyscraper's model = 5 feet

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.
