Question

На какое расстаяние мальчик переместил санки, приложив к шнурку санок 23 Н под углом 30 градусов и сделав работу 1,2 кДЖ. ПОмогите пж

Answer 1

A=F*S*cosa
S=A/F*cosa=1200/23*0,87=60 м

Answer 2

Calculating the Distance Moved by the Boy with the Sled

To calculate the distance moved by the boy when he applied a force of 23 N at a 30-degree angle and did 1.2 kJ of work, we can use the formula for work done:

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

Where: - W = 1.2 kJ = 1200 J (since 1 kJ = 1000 J) - F = 23 N - θ = 30 degrees

We can rearrange the formula to solve for distance (d):

Distance (d) = W / (F × cos(θ))

Let's calculate the distance using these values.
