Problem $2$

A $0\mathrm{.}15lbf$ bullet is fired horizontally into the $5lb$ block which rest on the $0\mathrm{.}22$ surface friction coefficient.

After the bullet becomes embedded into the block, the block moves to the right $3$ inches before momentarily coming to rest.

The spring has a stiffness of $200l\frac{b}{f}t.$ and is originally un$-$stretched.

Determine the speed in mph of the bullet before impact.

Una bala de $0\mathrm{.}15lbf$ es disparada horizontalmente hacia un bloque de madera de $5lbf$ que se encontraba en reposo. El coeficiente de fricci$ó$n entre el bloque y la superficie es de $0\mathrm{.}22.$

Despu$é$s que la bala se incrustara en el bloque, estos se deslizan $3$ pulgadas hacia la derecha y luego se queda en reposo moment$á$neamente$.$

$3sin(\frac{1f6}{10})=0\mathrm{.}25$

El resorte tiene un coeficiente de rigidez de $200lb\frac{f}{f}t$ & inicialmente est$ä$ sin deformarse.

Determine la velocidad de la bala ANTES del impacto en mph MUESTRE EL PROCEDIMIENTO PARA DETERMINAR LA VELOCIDAD de la bala antes del impacto
