A man of mass 50

Answer :

Weight of bag = 40N

G x mass of bag = 40 N

Where g = acceleration due to gravity = 9.8 ms–2

m1 = mass of bag

m2 = mass of man = 50 kg

total mass of man and bag system = (50 + 4.08) kg

= 54.08 kg

The N = Normal reaction that floor applies at static equilibrium.

Hence, the force with which the floor pushes up the feet = 530 N
