Un bloque con masa m = 2 kg se coloca contra un resorte sobre un plano inclinado sin fricción con ´Angulo θ = 30o(el bloque no está unido al resorte). El resorte, con constante de elasticidad k = 19.6 N/cm, se comprime 20 cm y luego se suelta. (a) ¿Cuál es la energía el' astica del resorte comprimido? (b) ¿Cuál es el cambio en la energía potencial gravitacional del sistema bloque-Tierra cuando el bloque se mueve del punto en que se suelta hasta su punto más alto en el plano inclinado? (c) ¿A que distancia a lo largo del plano inclinado está el punto más alto desde el punto en que se suelta el bloque?
