1.
Newton said, F= MA
where F = Force, M = Mass, A = Acceleration.
In this case, the acceleration is the acceleration due to gravity, or your "g".
You know his mass (95.0 kg), so figure out his mass at each location

2.
A Newton is a "Kg-M/Sec^2). The mass, in kilograms is determined from the above equation, F=MA where F = the force (in Newtons), M is the mass in Kg, A is the acceleration due to gravity.
