Question

J= 108 км/ч R=3мм m=6гр F=?​

Answer 1

Ответ:

Объяснение:

Дано:

V = 108 км/ч = 30 м/с

R = 3 мм = 0,003 м

m = 6 г = 0,006 кг

_______________

F - ?

F = m·V² / R

F = 0,006·30²/0,003 = 2·900 = 1 800 Н

Answer 2

To calculate the force (F), we can use the equation:

F = m * (J / R)

Given: J = 108 km/h R = 3 mm m = 6 g

First, let's convert the speed J from km/h to m/s: J_mps = J * (1000 m / 1 km) * (1 h / 3600 s) = 108 * (1000 / 1) * (1 / 3600) = 30 m/s

Next, let's convert the mass m from grams to kilograms: m_kg = m / 1000 = 6 / 1000 = 0.006 kg

Now we can calculate the force F: F = m_kg * (J_mps / R) = 0.006 * (30 / 0.003) = 0.006 * 10000 = 60 N

Therefore, the force (F) is 60 Newtons.
