You're sitting on the very top of the roof when Peter, who is on the edge of the roof, 5.5 m away, asks you for the box of nails.

If the coefficient of kinetic friction between the box and the roof is 0.54, with what speed should you push the box to have it gently come to rest right at the edge of the roof?
