A bucket full of water weighs 5 kg, it is pulled from a well 20 m deep. There is a small hole in the bucket through which water leaks at a constant rate. If it is observed that for every meter the bucket loses 0.2 kg mass of water, then the total work done in pulling the bucket up from the well is [g = 10ms^(-2) ]

How is water drawn up from a well by a water pump ?

Water is drawn from a well in a 5kg drum of capacity 55L by two ropes connected to the top of the drum. The linear mass density of each rope is 0.5kgm^-1 . The work done in lifting water to the ground from the surface of water in the well 20m below is [g=10ms^-2]

A ball of mass 5.0 gm and relative density 0.5 strikes the surface of the water with a velocity of 20 m/sec. It comes to rest at a depth of 2m. Find the work done by the resisting force in water: (take g = 10 m//s^(2) )

A rubber ball of mass 10 gram and volume 15 cm^3 is dipped in water to a depth of 10m. Assuming density of water uniform throughout the depth, find the acceleration of the ball ("Take g" =980 cm//s^2)
