Problem 32E

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 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?

Step-by-Step Solution:

Solution 32E Step 1 of 1: The energy of the box at the edge of the roof is given by: Emech(final) E mech(initial)fks 0 yi= 0 and y = f4.25)sin 36 = 2.5 m 1...
