7. En el extremo de un resorte de k=30N/m se gancha una masa de 0.5kg que descansa en reposo sobre una superficie sin friccion. Suponga que un proyectol de masa 0.015 kg se dispara dirigida al bloque y lo penetra y lo arrastra cierta distancia, si la velocidad del proyectol justo antes de hacer impacto es de 100 m/s encuentro, una & paso 1: Paso 2: pacto. Datos Vk V = W X A Paso 3: k= 30N/m W= Vm 1+ m2 m1= 0.5 kg A = V / w x(t) = A sen(wt + 8) m2= 0.015 kg 100 m/ s x(t) = 13.1 Sen (7.63t) W= V= 100 m/s A = 7.63 rad/s /30 N /m
