In 1985 in San Antonio, Texas, an entire hotel building was moved several

blocks on 36 dollies. The mass of the building was about 1.45 x 10^6 kg. If

1.00 x 10² MJ of work was done to overcome the force of resistance that

was just 2.00 percent of the buildings weight, how far was the building

moved?

The building was moved to a distance of, S = 510.2 m

Explanation:

Given data,

The mass of the building, m = 1.45 x 10⁶ kg

The work done to overcome the force of resistance, E = 1 x 10⁸ J

The force of resistance of the building, 2% of building weight

Fₓ = 2 x 1.45 x 10⁶ x 9.8 / 100

= 284200 N

The work done on the building,

E = Fₓ · S

∴ S = E / Fₓ

= 1.45 x 10⁶ / 284200 N

= 510.2 m

Hence, the building was moved to a distance of, S = 510.2 m
