At a distance of #3.84"m"# from the table.

We get the time of flight by considering Tom's vertical component of motion:

Since #u=0#:

#s=1/2"g"t^2#

#:.t=sqrt((2s)/("g"))#

#t=sqrt((2xx2)/(9.8))#

#t=0.64"s"#

Tom's horizontal component of velocity is a constant 6m/s.

So:

#s=vxxt#

#s=6xx0.64=3.84"m"#
