A 10 kg stone is suspended with a rope of breaking strength 30 kg-wt. The minimum time in which the stone can be raised through a height 10 m starting from rest is (Take, `g = 10 N kg^(-1)`).

Ramesh raises on object of 12 kg through a height of 2.0 m. The work done try him is (take g = 10 m//s ^(2)):

A monkey of 25 kg is holding a vertical rope. The rope does not break if a body of mass 30 kg is suspended with the rope exceeds 30 kg. What will be the maximum acceleration with which the monkey can climb up along the rope ? ( Take , =10 ms^(-2) )

A monkey of 25 kg is holding a vertical rope. The rope does not break if a body of mass less than 30 kg is suspended with the rope. What will be the maximum acceleration with which the monkey can climb up along the rope ? (Take g=10 ms^(-2) )

A body of mass 50 kg and specific gravity force is to be lifted using a rope of breaking strength of 60 kg wt. The acceleration with which it can be pulled up in least interval of time

A 5 kg stone of relative density 3 is resting at the bed of a lake. It is raised through a height of 5m in the lake. If g = 10 m//s^(2) , then work done is

A body of mass 60 kg is holding a vertical rope . The rope can break when a mass of 75 kg is suspended from it. The maximum acceleration with which the boy can climb the rope without breaking it is : ( g = 10 m//s^(2))
