Answer:
The force exerted by the legs on the person's upper body 32.106 N.
Given:
Mass = 69 kg
Acceleration = 1.45 [tex]\frac{m}{s^{2} }[/tex]
To find:
Force exerted by legs on the person's upper body = ?
Formula used:
Force = mass × acceleration
Solution:
Mass of legs = [tex]\frac{32}{100}[/tex] mass of body
Mass of legs = 22.08 kg
According to Newton's second law of motion,
Force = mass × acceleration
Force = 22.08 × 1.45
Force = 32.106 N
The force exerted by the legs on the person's upper body 32.106 N.
