- A vertical right-circular cylindrical tank measures 28 ft high and 14 ft in diameter. It is full of liquid weighing 62.4 lb/ft³. How much work does it take to pump the liquid to the level of the top of the tank? Set up the integral that gives the work required, in ft-lb, with y = 0 corresponding to the bottom of the tank. (Type an exact answer, using as needed.)Imagine a small moon with a mass equal to 1.3 times the mass of the Earth's moon. How much work is done y this moon on a 1,331 kg meteor which comes from outer space and impacts the surface of the moon? You should assume that the radius of this moon is equal to the radius of Earth's moon. Where the radius of Earth's moon = 1,738 km.A girl weighing 45kg is standing on the floor, exerting a downward force of 200N on the floor. The force exerted on her by the floor is
- Suppose that 6J of work is needed to stretch a spring from its natural length of 28 cm to a length of 40 cm. (a) How much work is needed to stretch the spring from 33 cm to 38 cm? (Round your answer to two decimal places.) 1.2 (b) How far beyond its natural length will a force of 2ON keep the spring stretched? (Round your answer one decimal place.) 7.5 cm Need Help? Watch ItA spring has a natural length of 6 m. If a 4-N force is required to keep it stretched to a length of 10 m, how much work W is required to stretch it from 6 m to 18 m?
