The 0.35$0\mathrm{.}35$ lbf ball is shot from the spring device shown. The spring has a stiffness k =12$=12$ lbf/$/$in.$.$ The plate reduces the spring to 1.5$1\mathrm{.}5$ inches in length, when its neutral length is 4$4$ inches. The plate remains in the position shown until a latch is removed which will cause the ball to be pushed down the sloping surface at 30$30$ degrees. Determine the speed of the ball as it moves 24$24$ inches up the sloping surface ,$,$ with a coefficient of kinetic friction of _$\_$k=0.15$=0\mathrm{.}15$ and the spring get it neutral length.ingrese la velocidad cuando la bola llega a las 24$24$ pulgadas en la rampa in ft/$/$s
