With what force does a person weighing 70kg press on the floor of an elevator moving vertically upward with an acceleration of 1m / s ^ 2?
To calculate the force of pressure of a person on the bottom of a given elevator with accelerated vertical ascent, we apply the formula: F = P = m * (g + a).
Values of constants and variables: m – human weight (m = 70 kg); g – acceleration of gravity (g = 9.81 m / s2); a – constant acceleration of the elevator (a = 1 m / s2).
Let’s calculate: F = m * (g + a) = 70 * (9.81 + 1) = 756.7 N.
Answer: With an accelerated vertical rise, the mass of a person will press on the bottom of a given elevator with a force of 756.7 N.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
