Question

Два тела движкться по взаимно перпендикулярным направлениям. масса первого тела равна 2 кг, а его скорость 3 м/с. масса второго равна 4 кг, скорость 2 м/с.Определить полный импульс системы

Answer 1

Вроде 10 кг м /c
p = mv
p1 = 6
p2 = 8
т.к. угол между ними 90
то p = √((p1)^2+(p2)^2)

Answer 2

P1=m*V=2*3=6 кг*м/с
P2=m2*V2=4*2=8 кг*м/с

P=√P1²+P2²=√100=10 кг*м/с

Answer 3

Calculation of the Total Momentum of the System

To determine the total momentum of the system, we need to calculate the momentum of each body and then add them together.

The momentum of an object is given by the product of its mass and velocity. Mathematically, it can be expressed as:

Momentum = mass × velocity

Let's calculate the momentum of each body:

- Body 1: - Mass (m1) = 2 kg - Velocity (v1) = 3 m/s - Momentum (p1) = m1 × v1 = 2 kg × 3 m/s = 6 kg·m/s

- Body 2: - Mass (m2) = 4 kg - Velocity (v2) = 2 m/s - Momentum (p2) = m2 × v2 = 4 kg × 2 m/s = 8 kg·m/s

Now, we can calculate the total momentum of the system by adding the individual momenta of the two bodies:

Total Momentum = Momentum of Body 1 + Momentum of Body 2

Total Momentum = p1 + p2 = 6 kg·m/s + 8 kg·m/s = 14 kg·m/s

Therefore, the total momentum of the system is 14 kg·m/s.
