Answer :
The weight of an object is (mass) x (gravity).
The weight of Mr. McDonald's object is (112) x (9.8) = 1,097.6 newtons.
(about 247 pounds)
That's the force pulling the object down, because it is near the Earth, and
the Earth and the object are attracting each other with forces of gravity.
In order to move the object away from the center of the Earth ("lift" it), a force greater than 1,097.6 newtons must be applied to it in the other direction ... upwards.
Any force greater than its weight will lift it. The more the upward force exceeds the minimum of 1,097.6 newtons, the faster Mr. McDonald's object will accelerate upwards.

Final answer:
To calculate the force required to lift a 112 kg object, use Newton's second law of motion. If more force is exerted than required, the object would still experience the same acceleration due to gravity. If less force is exerted, the object would not be lifted or would move slower.
Explanation:
To solve the problem of calculating the force required to lift a 112 kg object, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, since the object is being lifted vertically, the acceleration is equal to the acceleration due to gravity (9.8 m/s²).
So, the formula for calculating the force is F = m * a. Plugging in the values, we get F = 112 kg * 9.8 m/s² = 1097.6 N.
If Mr. McDonald exerts more force than the required 1097.6 N, the object would still experience the same acceleration due to gravity. However, if Mr. McDonald exerts less force, the object would not be lifted or would move at a slower rate.
