A person is on an elevator that moves downward with an acceleration of 1.8 ms squared. If the person weighs 686 n what is the net force on the person?

The net force on the person can be calculated using Newton's second law: F = m * a, where F is the net force, m is the mass of the person, and a is the acceleration. The weight of the person can be converted to mass using the formula weight = mass * acceleration due to gravity (9.8 m/s^2). Once you have the mass, you can plug it into the formula along with the given acceleration to calculate the net force.
