Question

U0=10м/с, U=20М/С m=200 t=2с найти F

Answer 1

F = am
$a = \frac{v - v0}{t}$
$a = \frac{20 - 10}{2} = 5 \frac{m}{c ^{2} }$
F = 5 * 200 = 1000 Н

Answer 2

To find the force (F) exerted on an object, you can use Newton's second law of motion, which states that the force (F) is equal to the mass (m) of the object multiplied by its acceleration (a):

F = m * a

Acceleration (a) can be calculated using the formula:

a = (U - U0) / t

where: U = final velocity of the object (20 m/s), U0 = initial velocity of the object (10 m/s), t = time taken for the object to change velocity (2 seconds).

Let's plug in the given values and calculate the acceleration:

a = (20 m/s - 10 m/s) / 2 s a = 10 m/s / 2 s a = 5 m/s^2

Now, we can calculate the force (F) using the given mass (m) of 200 kg:

F = m * a F = 200 kg * 5 m/s^2 F = 1000 N

So, the force exerted on the object is 1000 Newtons.
