## Question:

A box of weight ${ W }_{ 1 }$ slides from rest down the smooth ramp onto the surface of a cart of weight ${ W }_{ 2 }$. Determine the speed of the box at the instant it stops sliding on the cart. If someone ties the cart to the ramp at B, determine the horizontal impulse the box will exert at C in order to stop its motion. Neglect friction on the ramp and neglect the size of the box.Given: ${ W }_{ 1 }$= 40 lb , ${ W }_{ 2 }$ = 20 lb , h = 15 ft , g = ${ 32.2ft/s }^{ 2 }$
