Final answer:
The weight of a 10 kg apple falling from a tree is 98 Newtons.
Step-by-step explanation:
When an object is in free fall, it experiences only the force of gravity and no other forces. In this case, the apple is in free fall when falling from a tree, so we can use the principles of physics to determine its weight. The weight of an object is the force of gravity acting on it, and it is given by the equation:
Weight = mass x acceleration due to gravity
In this case, the mass of the apple is 10 kg and the acceleration due to gravity is approximately 9.8 m/s². Plugging these values into the equation, we can calculate the weight of the apple:
Weight = 10 kg x 9.8 m/s² = 98 N
Therefore, the apple weighs 98 Newtons when falling from a tree.
