You're sitting on the very top of the roof when Peter, who is at the edge of the roof directly below you, 5.0 meters away, asks you for the box of nails. Rather than carry the 2.5 kg box of nails down to Peter, you decide to give the box a push and have it slide down to him. If the coefficient of kinetic friction between the box and the roof is μ = 0.55, what initial speed should you give the box to have it gently come to rest right at the edge of the roof next to Peter?
