Question
A leaky 10-kg bucket is lifted from the ground to a height of 10 m at a constant speed with a rope that weighs 0.7 kg/m. Initially the bucket contains 30 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 10-m level. How much work is done? (Use 9.8 m/s² for g.) Show how to approximate the required work (in J) by a Riemann sum. (Let x be the height in meters above the ground. Enter x.* as x₁.) lim n→ ∞0 n i=1 Ax Express the work (in J) as an integral in terms of x (in m). dx Evaluate the integral (in J). (Round your answer to the nearest integer.) J
