A conical container of radius 6 ft and height 24 ft is filled to a height of 20 ft of a liquid weighing 62.4 lb/ft. How much work will it take to pump the contents to the rim? How much work will it take to pump the liquid to a level of 4 ft above the cone's rim? The amount of work required to pump the liquid to the rim of the tank is ft-lb. (Round to the nearest whole...

An electric elevator with a motor at the top has a multistrand cable weighing 4 lb/ft. When the car is at the first floor, 150 ft of cable are paid out, and effectively 0 ft are out when the car is at the top floor. How much work does the motor do just lifting the cable when it takes the car from the first floor to the top? The amount of work required is ft-lb. (Simplify your answer.)

A 1500-kg air conditioning unit is being lifted by a crane onto the roof of a building. The unit starts on the ground and is raised straight up to a height of 12.0 m by a cable attached to the crane. The tension in the cable during the lift is 1.54 × 104 N. (Reminders: a free body diagram will probably be helpful, and work can be positive or negative.) (a) How much work is done on the air conditioning...

4) A cylindrical can (radius 10 millimeters) is used to measure rainfall in Stormville. The can is initially empty and rain enters the can during a 60-day period. The height of water in the can is modeled by the function S, where S(t) is measured in millimeters and t is measured in days for 0sts 60. The rate at which the height of water is rising in the can is given by S'(t) = 2 sin(0.03t) of the 60-day period?...
