Aman weighs 650 n. inside a moving elevator, the floor exerts an upward force of 620 n on the man. what is the magnitude and direction of the man's acceleration?

Man's acceleration is 0.452 in downward direction

Explanation:

Weight of man, W= 650 N

Normal force exerted by floor of elevator , N= 620 N

Since weight , W = mg

mass m=

Using Newtons 2nd law

W-N= ma     where a= acceleration of man in the downward direction

=> 650-620=

=> a= 0.452 in downward direction

i don't know that i agree with that but what's the question ?

c) up

hope this
