Un bloque con una masa de 1.00 Kg parte desde el punto A con una velocidad de 5.00 m/s, y empieza su recorrido de bajada por un plano inclinado, el cual tiene una longitud de 5.00 m, una inclinación de 30.0°, y también en este tramo existe entre la masa y el plano un coeficiente de fricción cinético de 0.350. Finalmente el bloque recorre el tramo horizontal BC sin fricción, donde al final se tiene un resorte con una constante elástica de 500 N/m, que posteriormente será comprimido por el impacto del bloque (ver figura 1). Para la situación anterior se pide determinar: a) ¿Cuál será la rapidez de la masa cuando llega al extremo inferior del plano?
b) ¿Cuál es el trabajo que realiza la fuerza de fricción desde el punto A, hasta el final del plano inclinado? c) ¿Cuál será la rapidez de la masa un instante antes de impactar al resorte?
d) Si ahora consideramos el sistema de la figura 2, ¿Cuál será la rapidez de la masa cuando pasa por el punto B?. Considere entre los puntos A y B el mismo coeficiente de fricción.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
