a 700 N man stands on a scale on the floor of an elevator. The scare records the force it exerts on whatever is on it. What is the scale reading if the elevator has an acceleration of 1.8 m/s squared up ? I need help with what formula (s) to use to get the answer. I didn't understand the answer when I plugged in the numbers.

f=m (g+a)
f= 700 (9.81 + 1.8)

help..... not sure what to do

you have to enter mass for m.

700N is not mass, but weight.
mass= 700/9.8 kg
