Question

A man of mass 60 kg is standing in a lift and lift is moving upward with an acceleration of 4.9 what is the foce

Answer 1

Answer:

Mass of the man (m)=60 kg

acceleration of the man (a)=4.9m/s sq.

as the acceleration of the lift is equal to the acceleration of the man

now, using F=ma

F=60kg. 4.9m/s sq.

F=294 kgm/s sq.

F=294 N

I hope the unit of acceleration may be the same I took
