A 0.1 kg popped is placed on a table. When it pops up, it reaches a height of 2.0 meters. What was the initial velocity of the popper of the table?

assuming all energy goes into KEnergy,
max PE=maxKE
mgh=1/2 mv^2
v=sqrt(2gh)=sqrt(2*9.8*2)

I have gathered that it is either .2, 1.96, 6.26, or 39.2.
