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 function is considered exponential when it has a base with positive values greater than zero and different from one, where the exponent is an unknown. An important characteristic of exponential functions is that they show rapid growth or decay as an independent variable increases or decreases. Given the function 25^(x+3)=125, it is calculated that x has the value of
(X+2)(x+3)=4x+18
