While a roofer is working on a roof that slants at 43.0 ∘ abovethe horizontal, he accidentally nudges his 90.0 N toolbox, causingit to start sliding downward, starting from rest.
If it starts 4.75 m from the lower edge of the roof, how fastwill the toolbox be moving just as it reaches the edge of the roofif the kinetic friction force on it is 22.0 N ?
