Question

A man in a lift is moving upwards in a constant speed.the weight of the man is W.Acc

ording to Newtons third law,the reaction force of the weight W is the force of ?​

Answer 1

Normal force=mg

Step-by-step explanation:

The reaction force of weight is the normal force.

in order to find the normal for we need to write all the forces and set it equal to the net force:

N-mg=ma (since it is a constant speed the a=0)

N=mg
