Question

Сила 50 н сообщает телу ускорение 0,75 м /с какая сила сообщит этом телу ускорение 2 м/с

Answer 1

F = am
m = F \ a
m = 50 \ 0,75 = 66,67 кг
F = 2 * 66,67 = 133,34 Н

Answer 2

To calculate the force required to produce a specific acceleration for an object, you can use Newton's second law of motion, which states that force (F) is equal to the mass (m) of the object multiplied by its acceleration (a). The formula is:

F = m * a

Given the information:

Force (F₁) = 50 N (when acceleration is 0.75 m/s²) Acceleration (a₂) = 2 m/s²

Let's assume the mass of the object remains the same for both cases.

Now, we can calculate the force required to produce an acceleration of 2 m/s² using the same mass as before.

F₂ = m * a₂

Since we are assuming the mass (m) is constant in both scenarios, we can use the force-acceleration relationship from the first case (F₁ = 50 N and a₁ = 0.75 m/s²) to find the value of mass (m):

F₁ = m * a₁ 50 N = m * 0.75 m/s²

Now, let's find the mass (m):

m = 50 N / 0.75 m/s² m = 66.67 kg

Now that we know the mass (m) is approximately 66.67 kg, we can calculate the force (F₂) required to produce an acceleration of 2 m/s²:

F₂ = m * a₂ F₂ = 66.67 kg * 2 m/s² F₂ = 133.34 N

So, the force required to produce an acceleration of 2 m/s² on the same object is approximately 133.34 N.
