## Question:

The projectile of weight W is fired from ground level with initial velocity ${ v }_{ A }$ in the direction shown. When it reaches its highest point B it explodes into two fragments of weight W/2. If one fragment travels vertically upward at speed ${ v }_{ 1 }$, determine the distance between the fragments after they strike the ground. Neglect the size of the gun. Given: W = 10 lb , ${ v }_{ A }$ = 80 ft/s , ${ v }_{ 1 }$ = 12 ft/s , θ = 60 deg , g = ${ 32.2ft/s }^{ 2 }$
