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