Answer:
=19.6N
Explanation:
The force exerted by the object on the surface of the Earth as it falls is equal to its weight, which is the force due to gravity acting on the object.
The weight of an object can be calculated using the formula:
Weight=mass×acceleration due to gravity
Given:
Mass (m) of the object = 2 kg
Acceleration due to gravity (g) near the surface of the Earth is approximately 9.8m/s
Substituting the values into the formula:
Weight=2kg×9.8m/s2=19.6
=19.6N
Therefore, the force exerted by the object on the surface of the Earth as it falls is approximately
19.6N
