Lucy and her friend are working at an assembly plant making wooden toy giraffes. At the end of the line, the giraffes go horizontally off the edge of the conveyor belt and fall into a box below. If the box is 0.6 m below the level of the conveyor belt and 0.4 m away from it, what must be the horizontal velocity of giraffes as they leave the conveyor belt?

It takes t seconds the giraffes to reach the bottom of the belt:

$t=\sqrt{\frac{-2y}{g}}=\sqrt{\frac{-2\cdot (-0.6)}{9.8}}=0.35s$

The velocity of the giraffes must be:

$v}_{x}=\frac{x}{t}=\frac{0.4}{0.35}=1.1\frac{m}{s$

The velocity of the giraffes must be:

Since the giraffes are going off horizontally, there is noinitial vertical velocity
