Answer:
The force acting on the free-falling object is, F = 1.47 N
Step-by-step explanation:
Given data,
The mass of the object, m = 150 g
When an object is under free-fall, the only force acting on the object is the gravitation force neglecting the air resistance.
So, when an object is close to the surface of the earth acceleration due to gravity acting on the object is equal to g.
The value of g at the surface of the Earth is, g = 9.8 m/s²
Therefore, the force acting on the object under free fall is,
F = mg
= 0.15 x 9.8
= 1.47 N
Hence, the force acting on the free-falling object is, F = 1.47 N
