Question

A man of mass 100 kg is standing in an elevator. The net force on man when elevator is going on with acceleration of 4m/s-2 would be :
a:908N
b:490N
c:100N
d:1380N​

Answer 1

Answer:

F=ma=(100kg)(4m/s/s)=400N

N is Newton, the SI unit of force, which is a kg•m/s/s. F is net force and, of course, m is mass and a is acceleration.
