Solución: El trabajo realizado por la fuerza de fricción está dado por W_f=fd dónde f es la fuerza de fricción entre el objeto y la superficie, y d es la distancia recorrida por el objeto. Según el teorema de Pitágoras, la distancia recorrida es d=\sqrt{x^2+y^2}

d=\sqrt{8.3^2+4^2}

d\aproximadamente9.214m Por tanto, el trabajo realizado es W_f=112\cdot9.214 W_f\aprox1031.921J Respuesta: 1031,921 julios

A construction company is working on two projects: house construction and building construction. Each house requires 4 weeks of work and produces a profit of $50,000. Each building requires 8 weeks of work and produces a profit of $100,000. The company has a total of 24 work weeks available. Furthermore, it is known that at least 2 houses and at least 1 building must be built to meet the demand. The company wants to maximize its profits and needs to determine how many houses and buildings it should build to meet demand and maximize profits, given time and demand constraints.
