Question

A 93.7 kg boxer has his first match in the Canal Zone withgravitational acceleration 9.782 m/s2. 1. What is his mass in the Canal Zone? answer in units of kg. 2. What is his weight in the Canal Zone? answer in units of N 3. What is his mass at the North Pole? answer in units of N 4. What is his weight at the North Pole? answer in units of N I really need help on this one; I'm totally confused.

Explanation / Answer

1. 93.7kg 2. F = ma = (93.7kg)(9.782m/s2 ) = 916.5734N 3. 93.7kg 4. F = ma = (93.7kg)(9.81m/s2 ) = 919.197N An object's (or person's) mass is constant no matter where they are(Canal Zone, Canada, the Moon, etc.). An object's (or person's)weight is their mass times the gravitational acceleration ofwherever they are (the force of their mass being pulled down by(usually) the earth's gravitational field). The earth'sgravitational field varies very little, and can usually be taken asthe contant g = 9.81m/s2. Gravitational accelerationdecreases with increase in altitude, so a person may seem lighterat higher elevations. In the Canal Zone, for example, the person is'lighter' because gravity is less strong than standard(9.81m/s2 ). In your post, you request number three be answered in Newtons, butthat is a measure of force, not mass. I assumed it was amistype. Also, you did not give the value for the acceleration at the NorthPole. I don't know what it is, but I assumed it to be9.81m/s2 . If it is different, simply change the numberfor the correct answer.
