A man of mass 50 kg carries a bag of we500 N on his shoulder. The force with whichfloor pushes up his feet will be (g = 9.8 m/s​

Answer»

Answer :-

  • The force with which floor PUSHES up his feet will be 540N.

Step-by-step EXPLANATION:

To Find :-

  • The force with which floor pushes up his feet

Solution:

Given that,

  • g = 9.8 m/s
  • A man of MASS 50kg carries a BAG of weight 500N

Therefore,

Mass of the bag :-

⟶ m × a = F

⟶ m × 9.8 = 500

⟶ m = 500/9.8

⟶ m = 51.02 kg

So, Total mass:- [ mass of man + mass of bag ],

⟶ Total mass = 50kg + 51.02kg

⟶ [ 50 + 51.02 ] kg

⟶ 101.02 kg

∴ The force with which floor pushes up his feet is :-

  • F = a × m

Where,

  • F = Force
  • a = acceleration due to gravity
  • m = Mass

⟶ F = m × a

⟶ F = 51.02 × 9.8

⟶ F = 499.99N

Hence, The force with which floor pushes up his feet is 499.99N.
