N that acts through a distance of$0\mathrm{.}500$ m$.$ How much KE did the puck have before the push?

How much work was applied to it$?$

How much KE does the puck have after getting pushed?

How much work would be required to bring the puck to rest?

How far would the puck slide if a I $\mathrm{.}00$ N force opposed its motion?

How far would the puck slide against a $3\mathrm{.}00$ N ODDOSinu force?
