A stationary object at `4^(@)C` and weighing `3.5 kg` falls from a height of `2000 m` on a snow mountain at `0^(@)C.` If the temperature of the object just before hitting the snow is `0^(@)C `and the object comes to rest immediately? (g=`10m//s^(2)` and heat of ice =`3.5xx10^(5)` joule `//`sec), then the object will melt

A stationary objected at 0^(@)C and weighing 3.5 kg falls from a height of 2000m on a snow mounation at 0^(@)C . If the temperature of the object just before hitting the snow is 0^(@)C and the object comes to rest immediately (g = 10 m//s^(2)) and (latent heat of ice = 3.5 xx 10^(5) "joule"//s) then the mass of ice that will melt is -
