Question:

A ball of weight W is thrown in the direction shown with an initial speed ${ v }_{ A }$. Determine the time needed for it to reach its highest point B and the speed at which it is traveling at B. Use the principle of impulse and momentum for the solution. Given: W = 2 lb , θ = 30 deg , ${ v }_{ A }$ =18 ft/s , g = ${ 32.2ft/s }^{ 2 }$
