## Question:

Block A has weight ${ W }_{ A }$ and block B has weight ${ W }_{ B }$ . If B is moving downward with a velocity ${ v }_{ B0 }$ at t = 0, determine the velocity of A when t = ${ t }_{ 1 }$ . Assume that block A slides smoothly. Given: ${ W }_{ A }$ = 10 lb , ${ W }_{ B }$ = 3 lb , ${ v }_{ B0 }$ = 3 ft/s , ${ t }_{ 1 }$ = 1 s , g =${ 32.2ft/s }^{ 2 }$
