Ok This is a Calculus assignment question but more of af physics thing.. First were using integrals so there is the first part. I understand Intergration and all it jusst how to get a equation to apply it to is the hard part. a 4 lb bucket is lifted 80 Ft from a bottom of a well full of water. the water in bucket weighs 40lb but is leaking out of a hole at a rate of .2 lb/s. It rate of accent is 2 ft/s. As far as I can tell there will be a constant in the equation since a 4lb bucket will rise 80 ft. so that is constant thye whole time.. but since the water is leaking how do i use that rate of change in with the speed. Plus I am figure this out in the British system.. Lb/ft not metric newton joules. so a far as i got i would have 4*80 + (40-.2x)/2 As far as I can figure i would have to use that formula.. but it just doesn't look right or sound right..
