Question

Сила 100 ньютонов совершила работу 100кдж какой путь прошло тело? Хелп

Answer 1

A=Fs

s=A/F

A=100 кДж=100000 Дж

s=100000 Дж/100Н=1000 м

s=1 км

Answer 2

To calculate the distance (path) traveled by the body, we can use the work-energy principle, which states that the work done on an object is equal to the change in its kinetic energy. The formula for work is:

Work (W) = Force (F) × Distance (d) × cos(θ)

where: W = 100 kJ = 100,000 J (since 1 kJ = 1000 J) F = 100 N θ = the angle between the force vector and the direction of motion (since it's not given, we assume θ = 0 degrees, which means the force is applied in the direction of motion) d = the distance traveled (what we need to find)

Now, we can rearrange the formula to solve for distance (d):

d = W / (F × cos(θ))

Substitute the given values:

d = 100,000 J / (100 N × cos(0°))

cos(0°) = 1 (cosine of 0 degrees is 1)

d = 100,000 J / (100 N × 1) d = 1000 m

Therefore, the body traveled a distance of 1000 meters (1 kilometer).
