Calculate the worked done in lifting a 300N weight to a height of 10m with an accelertaion `0.5ms^(2)`. Take g=`10ms^(-2)`.

500 J of work is done in lifting a 30 kg weight to a height of 0.5 m . With what acceleration the weight was raised ?

230 joules were spent inlifting a 10kg wieight to a height of 2m. Calculate the acceleration with which it was raised Take g= 10ms^(2) .

A crane lifts a mass of 100 kg to a height of 10m in 20s . The power of the crane is (Take g = 10 ms^(-2))

Calculate the work done in lifting 200 kg of water through a vertical height of 6 meters (Assume g = 10 m//s^(2) ).

An object of mass 5 kg is attached to the hook of a spring balance and the balance is suspended vertically from the roof of a lift. The reading on the spring balance when the lift is going up with an acceleration of 0.25 ms^(-2) is take, (take, g=10ms^(-2) )

A 75 kg man stands in a lift. What force does the floor does the floor exert on him when the elevator starts moving upwards with an acceleration of 2.0ms^(-2) . ? Take g = 10 ms^(-2) .

Find the work done of move an object of mass 3 kg to a height of 20 m from the ground (Take g =10ms^(-2) ).
