Well, let's see. We can change that equation to N= ma + mg.The force balance on the man is $$N-mg=ma$$where N is the upward force that the scale exerts on the man, mg is the downward force of the Earth on the man, and a is the upward acceleration. Does that make sense?
ma =(61.2*11.8)= 722.2
mg= (61.2*9.8)= 599.8
So N=1322 N--am I understanding this correctly?
