Calculus Thomas 14th edition. Ch.6.5, problem 13. A 5 kg bucket lifted from the ground into the air by pulling in 20 m of rope at a constant speed. The rope weighs 0.08 kg/m. The work spent on bucket and rope is 1136.8 J. Assume that the bucket is leaking it starts with 5 liters of water (5 kg ) and leaks at the constant rate. It finishes draining just as it reaches the top. How much work was spent...

On Earth, a wooden block of mass mb= 0.5 kg hangs from the ceiling by a very long, massless string. A chunk of putty of mass mp= 0.25 kg, starting at a distance of 10 m away from the block is thrown vertically upward at an initial speed of +35 m/s toward the block, striking the block and sticking to it. How high does the putty-block system rise above the original position of the wooden block?
