Answer 1

Complete question please

Answer 2

Given, Weight = 40N and mass= 50 Kg.

We know that, F=ma  

                       40N = m x g

                       40/g = m

                      40/10 = m

                      4kg = m

                    mass = mass of man + mass of bag

                             = 50 + 4

                            = 54 kg

Force with which the floor pushes up his feet,

                      

                      F = ma

                     F  = 54 x g

                     F = 54 x 10

                        = 540N.

that's it
