Answer :

The force exerted on the floor by a person with a mass of 114 kg, due to gravity alone, is 1,117.2 N.

To calculate the force a person exerts on the floor, we can use Newton's second law of motion which states that force equals mass times acceleration (F = ma).

If the person's mass is 114 kg, and assuming the acceleration due to gravity (g) is 9.80 m/s2.

The force exerted on the floor while the person is just standing is the gravitational force or weight (W = mg).

Therefore, the force is:

F = m * g

F = 114 kg * 9.80 m/s2

F = 1,117.2 N

The acceleration while he is straightening his legs would involve a different calculation and more information would be required.

Typically, to find acceleration, we would also need the time it takes to reach the final velocity.

Thanks for taking the time to read Calculate the force in N he exerts on the floor given that his mass is 114 kg. We hope the insights shared have been valuable and enhanced your understanding of the topic. Don�t hesitate to browse our website for more informative and engaging content!
