1. A 95.0 kg (209 lb) boxer has his first match in the Canal Zone (g = 9.782 m/s^2) and his second match at the North Pole (g = 9.832 m/s^2).
a. What is his mass in the Canal Zone?
b. What is his weight in the Canal Zone?
c. what is his mass at the North Pole?
d. What is his weight at the North Pole?
e. Does he "weight in" or does he really "mass in"?


2.then your new motorcycle weights 2450 n. What is its mass in Kilograms?
*(I don't know how to go from n to kg) (how many kg and in 1 n)*

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.
