Question

Марио массой 90 кг прыгает с платформы на платформу Высота первой платформы 10 м, а высота второй 6 м Какую работу совершит сила тяжести, если ускорение свободного падения в мире Марио равно 8H/кг

Answer 1

Ответ:

Объяснение:

Работа силы тяжести:

А = m·g· (h₁ - h₂)

A = 90·8·(10 - 6) = 2 880 Дж

Answer 2

Calculation of Work Done by Gravity

To calculate the work done by gravity when Mario jumps from one platform to another, we need to determine the change in height and the force of gravity acting on Mario.

Given: - Mass of Mario (m) = 90 kg - Height of the first platform (h1) = 10 m - Height of the second platform (h2) = 6 m - Acceleration due to gravity (g) = 8H/кг (from the question)

The work done by gravity can be calculated using the formula:

Work = Force x Distance

The force of gravity acting on Mario can be calculated using the formula:

Force = Mass x Acceleration due to gravity

Let's calculate the force of gravity first:

Force = 90 kg x 8H/кг

Now, let's calculate the work done by gravity when Mario jumps from the first platform to the second platform:

Work = Force x Distance

The distance is the difference in height between the two platforms:

Distance = h1 - h2

Substituting the values into the formulas, we can calculate the work done by gravity.

Calculation:

Force = 90 kg x 8H/кг Distance = 10 m - 6 m

Work = Force x Distance

Now, let's calculate the values:

Force = 90 kg x 8H/кг = 720H

Distance = 10 m - 6 m = 4 m

Work = 720H x 4 m = 2880H

Therefore, the work done by the force of gravity when Mario jumps from the first platform to the second platform is 2880H.

Please note that the unit "H" in the calculation represents the acceleration due to gravity, which is given as 8H/кг in the question.
