Question

Дано:m=2тV0=0S=100мдельта t=10сНайти:F-?

Answer 1

F=m*a, где а=(2*S/t$^{2}$) из формулы S=(a*t$^{2}$)/2
a=(2*100)/10$^{2}$=200/100=2m/c$^{2}$
F=2000кг*2м/с$^{2}$=4000Дж=4кДж
Ответ: F=4кДж

Answer 2

Given:

- Mass (m) = 2 т (tonnes) - Initial velocity (V0) = 0 - Displacement (S) = 100 м (meters) - Time interval (Δt) = 10 с (seconds)

To find:

- Force (F)

Solution:

To find the force (F), 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.

The acceleration of an object can be determined using the following equation: a = (V - V0) / t where: - a is the acceleration - V is the final velocity - V0 is the initial velocity - t is the time interval

In this case, the initial velocity (V0) is given as 0, so the equation simplifies to: a = V / t

We can rearrange this equation to solve for the final velocity (V): V = a * t

To find the force (F), we can substitute the values for mass (m) and acceleration (a) into the equation: F = m * a

Now, let's calculate the acceleration (a) using the given values: a = (V - V0) / t = (S / t - V0) / t = (100 м / 10 с - 0) / 10 с

Substituting the values into the equation: a = 10 м/с²

Finally, we can calculate the force (F): F = m * a = 2 т * 10 м/с² = 20 т * м/с²

Therefore, the force (F) is 20 т * м/с².
