While a roofer is working on a roof that slants at 36
Chapter 7, Problem 7.32(choose chapter or problem)
While a roofer is working on a roof that slants at 36 above the horizontal, he accidentally nudges his 85.0-N toolbox, causing it to start sliding downward, starting from rest. If it starts 4.25 m 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 22.0 N?
