How Far Was the Hotel Building Moved in San Antonio, Texas?

In summary, an entire hotel building in San Antonio, Texas was moved several blocks on 36 dollies in 1985. The building had a mass of 1.45 x 10^6 kg and it took 1.00 x 10^2 J of work to overcome the force of resistance, which was only 2.00 percent of the building's weight. Using the equation for net work, the distance the building was moved can be calculated. The formula for friction force can also be used to find the distance.

Homework Statement



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 10^2 J of work was done to overcome the force of resistance that was just 2.00 percent of the building's weight. How far was the building moved?

Homework Equations



Net Work = deltaKE or deltaKE = KE(final) - KE(initial) = -1/2mv(initial)^2

The Attempt at a Solution



I'm confused on what to look for first and what formula to use.
Could someone please help me out?
Thank You.

Friction force= (coeff of friction)(Weight)(gravity)

Work = Force*distance
 

FAQ: How Far Was the Hotel Building Moved in San Antonio, Texas?

What is work and energy?

Work and energy are two fundamental concepts in physics. Work is defined as the transfer of energy from one object to another by the application of a force. Energy, on the other hand, is the ability to do work.

What is the relationship between work and energy?

The relationship between work and energy can be described by the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy. In other words, the amount of work done on an object is directly proportional to the change in its energy.

How do you calculate work and energy?

The formula for calculating work is W = F * d, where W is work, F is the force applied, and d is the distance over which the force is applied. The formula for calculating energy is E = m * g * h, where E is energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.

What are the different forms of energy?

There are several forms of energy, including kinetic energy, potential energy, thermal energy, electrical energy, and chemical energy. Kinetic energy is the energy an object possesses due to its motion, while potential energy is the energy an object has due to its position or state. Thermal energy is the energy associated with the temperature of an object, and electrical energy is the energy associated with the movement of charged particles. Chemical energy is the energy stored in the bonds between atoms.

How can work and energy be applied in real-world situations?

Work and energy are essential concepts in understanding various phenomena in the real world, such as the movement of objects, the production of electricity, and the functioning of machines. They can also be applied in fields like engineering, architecture, and environmental science to solve problems and design efficient systems.
