Question:

The block of weight W has an initial velocity ${ v }_{ 1 }$ in the direction shown. If a force F = {${ f }_{ 1 }$i + ${ f }_{ 2 }$j} acts on the block for time t, determine the final speed of the block. Neglect friction. Given: W = 2 lb , a = 2 ft , ${ f }_{ 1 }$ = 0.5 lb , ${ v }_{ 1 }$ = 10 ft/s , b = 2 ft , ${ f }_{ 2 }$= 0.2 lb , g = ${ 32.2ft/s }^{ 2 }$ , c = 5 ft , t = 5 s
