#"a".61"kg"# and #"b".133"lbs"#

Explanation:

The weight of an object is the force of gravity acting on it. On earth, we know that this is

  • #W=F_G=mg#

where #m# is the mass of the object and #g# is the gravitational or free-fall acceleration constant

  • Given the force #F_G=600"N"# and that #g=9.81"m"//"s"^2#:

#F_g=mg#

#=>m=F_g/g#

#=>=(600"N")/(9.81"m"//"s"^2)#

#=>~~61"kg"#

His weight in pounds is found either by multiplying the answer above by #~~2.2("lb")/"kg"# or by dividing the given force by #(4.45"N")/"lb"#

#=>600/4.5~~133" lbs"#
