We know

#"Unit of energy"#

#=("unit of mass"xx"unit of length"^2)/"unit of time"^2#

#"So New Unit of energy"#

#=(10kgxx(10m)^2)/"min"^2->"considering new system"#

#=(10kgxx(10m)^2)/"60s"^2#

#=(10kgxx(10m)^2)/(3600s^2)#

#=5/18xx(kgm^2)/s^2#

#=5/18xxNm=5/18J=1/3.6J#

So #" "1J=3.6xx"New unit of energy"#

Hence the numeric value of 1J in new system is 3.6
