Question

Сила 40Н сообщает телу ускорение 2м/с^2 Какая сила сообщит этому телу ускорение 3м/с^2

Answer 1

дано F1=40 Н    a1=2м\с2     а2=3 м\с2     F2-?

F2\F1=m^a2\m*a1

F2=40*3\2=60 Н

Answer 2

To find the force that will give the object an acceleration of 3 m/s^2, we can use Newton's second law of motion, which states:

Force (F) = mass (m) × acceleration (a)

Given that the force of 40 N gives the object an acceleration of 2 m/s^2, we can rearrange the equation to find the mass (m) of the object:

mass (m) = Force (F) / acceleration (a)

Now, we can calculate the mass of the object:

mass (m) = 40 N / 2 m/s^2 = 20 kg

Now that we know the mass of the object is 20 kg, we can find the force required to give the object an acceleration of 3 m/s^2:

Force (F) = mass (m) × acceleration (a)

Force (F) = 20 kg × 3 m/s^2 = 60 N

So, the force that will give the object an acceleration of 3 m/s^2 is 60 N.
