Question

Fred has a mass of 50 kilograms on Earth. What would his mass be on the Moon?

Answer 1

Mass of an object is a constant (unless if it broken up, etc.). It does not change whether it is in the gravitation force of the Earth, Moon, or "weightless" in space.

Answer 2

A car is being pulled by a tow truck. What is the car’s mass if the net force on the car is 3,000N and it has an acceleration of 2.0 m/s/s.

Answer 3

One Newton is the force that results from a 1 kg mass subjected to an acceleration of 1 meter per second squared (or 1 N =1 kg * 1 m/s^2). You can calculate the mass of the car by dividing the force by the acceleration ( mass = force in N / acceleration in m/s^2 ).

Answer 4

btw, m/s^2 is m/s/s
