Question

Два шарика массы которых m и m3,движутся со скоростями соответственно 2u и u навстречу друг другу . чему равен модуль полного импульса системы

Answer 1

Если подразумевалось 3m, то модуль полного импульса mu.

Answer 2

Calculating the Total Impulse of the System

To calculate the total impulse of the system, we can use the formula:

Total Impulse = Change in Momentum

The change in momentum is given by the formula:

Change in Momentum = Final Momentum - Initial Momentum

The momentum of an object is given by the product of its mass and velocity:

Momentum = mass * velocity

Given that the two objects are moving towards each other, the total impulse of the system can be calculated using the above formulas.

Calculation Steps

1. Calculate the momentum of the first object. 2. Calculate the momentum of the second object. 3. Add the momenta together to find the total impulse of the system.

Momentum Calculation

The momentum of an object is given by the product of its mass and velocity. In this case, the two objects have masses m and m3, and velocities 2u and u respectively.

1. Momentum of the first object: - Momentum = mass * velocity - Momentum of the first object = m * 2u

2. Momentum of the second object: - Momentum = mass * velocity - Momentum of the second object = m3 * u

Total Impulse Calculation

The total impulse of the system is the sum of the momenta of the two objects.

Total Impulse = Momentum of the first object + Momentum of the second object

Total Impulse = m * 2u + m3 * u

This is the calculation for the total impulse of the system based on the given masses and velocities.
