Question

Определите суммарную работу сил, которая будет совершена, если сила, равная 3 Н, поднимет груз массой 100 г на высоту 5 м.

Answer 1

А=А1+А2, где А-суммарная работа сил, А1-работа силы, А2-работа силы тяжести. А1=F*h;A2=-P*h, где P-вес тела.Найдем А=F*h-P*h; A=3*5-1*5=10Дж

Answer 2

Calculating Work Done by a Force

To calculate the work done by a force lifting a mass to a certain height, we can use the formula:

Work (W) = Force (F) × Distance (d)

Given: - Force (F) = 3 N - Mass (m) = 100 g = 0.1 kg - Height (h) = 5 m

Using the formula, we can calculate the work done by the force.

Work (W) = Force (F) × Distance (d)

Work (W) = 3 N × 5 m

Work (W) = 15 J

The work done by the force lifting the mass to a height of 5 m is 15 Joules.

This calculation is based on the formula for work and the provided values for force and distance.
