Question

Сила 60 H сообщает телу ускорение 0,8м/c^2 .Какая сила сообщит этому телу ускорение 2м/с^2?Ответ выразить в СИ

Answer 1

M₁=m₂            применим 2-й закон Ньютона:
a₁=0,8 м/с²            F₁=m₁a₁   ⇒   m₁=F₁/a₁;  т. к. m₁=m₂, то
F₁=60 H                 F₂=m₂a₂=F₁a₂/a₁;
a₂=2 м/с²               F₂=60*2/0,8=150 H;
_________             Ответ: F₂ =150 Н.
F₂-?

Answer 2

Given Information:

- Force (F) = 60 H - Acceleration (a) = 0.8 m/s^2

Calculation:

To find the force that will give the body an acceleration of 2 m/s^2, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration:

F = m * a

Since we are given the force and the initial acceleration, we can rearrange the equation to solve for mass (m):

m = F / a

Substituting the given values:

m = 60 H / 0.8 m/s^2

Now we can calculate the mass:

m = 75 kg

Now that we have the mass, we can calculate the force required to give the body an acceleration of 2 m/s^2:

F = m * a

Substituting the values:

F = 75 kg * 2 m/s^2

Answer:

The force required to give the body an acceleration of 2 m/s^2 is 150 N.
