Question

what ia the weight if a object who mass is 58 kg​

Answer 1

Explanation:

If the mass of the body is 58 kg, then that's its mass. If you're talking about weight, that's different. The weight of the object at the center of the Earth is zero. At the poles it's 58 kg * 9.83 N/kg, or 570 N.

Answer 2

Explanation:

Weight is given by the formula,

#W=mg#

#W# is the weight of the object in newtons

#m# is the mass of the object in kilograms

#g# is the gravitational acceleration

On Earth, #g=9.8 \ "m/s"^2#. So, the object's weight on Earth will be:

#W=50 \ "kg"*9.8 \ "m/s"^2#

#=490 \ "N"#
