hi,


6000 J of work which is done is converted into gravitational potential energy (neglecting friction) assume g=10m/s2


6000=m*10*20


m=30kg.


plzzzz approve!!!!!!!!!!!!!!!!!!!!!

workdone against gravity  = mgH


 m=? , g = 10 , H =20 so


W(gravity) = 200m


W = 6000 is given so


200m = 6000


   m = 30kg
