Question

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

Answer 1

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.
