Question: 2.(5 points) A container is lifted vertically at the rate of 2 feet per second. Water is leaking out of the container at the rate

2.(5 points) A container is lifted vertically at the rate of 2 feet per second. Water is leaking out of the container at the rate of $1/2$ pound per second. If the initial weight of water and container is 20 pounds, find the work $ W $ done in raising the container 10 feet. Give an exact answer (i.e. no decimal approximations).(Hint: For $0\leq y \leq 10$, determine the total weight of water and container when the container has been raised $ y $ feet.)
