While a roofer is working on a roof that slants at 39.0? above the horizontal, he accidentally nudges his 90.0N toolbox, causing it to start sliding downward, starting from rest.

If it starts 4.70m from the lower edge of the roof, how fast will the toolbox be moving just as it reaches the edge of the roof if the kinetic friction force on it is 21.0N?
