Question
While a roofer is working on a roof that slants at 45.0? above the horizontal, he accidentally nudges his 95.0N toolbox, causing it to start sliding downward, starting from rest.If it starts 4.30m 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 20.0N ? v=? m/s While a roofer is working on a roof that slants at 45.0? above the horizontal, he accidentally nudges his 95.0N toolbox, causing it to start sliding downward, starting from rest.
