Un bloque de 3 kg en reposo se deja libre a una altura de 5 m sobre una rampa curva y sin rozamiento. Al pie de la rampa se encuentra un resorte de constante k = 400 N/m, como se muestra en la fig. El objeto desliza por la rampa y llega a chocar contra el resorte comprimiéndolo una distancia x antes de que quede en reposo momentáneamente. Determinar: a) La velocidad con la que el bloque alcanza al resorte. b) La distancia x que el bloque comprime al resorte. c) La velocidad con la que el bloque es expulsado por el resorte. d) La altura que alcanza sobre la parte curva. e) ¿Alcanzará la misma altura si la rampa no está libre de rozamiento?
