Question

Тело массой 1кг изменило свою скорость на 2м/с. Опредилите импульс силы действующий на тело

Answer 1

Импульс (p)= mv Решение: Воспользуемся вторым законом Ньютона в импульсной форме: Соответственно, получается : 2 кг * м / с Подробное объяснение прилагается фотогоафией .

Answer 2

Calculation of Impulse

To calculate the impulse exerted on an object, we can use the formula:

Impulse = Change in momentum

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

Momentum = mass × velocity

In this case, we are given that the mass of the object is 1 kg and it changes its velocity by 2 m/s. Therefore, we can calculate the impulse as follows:

Impulse = Change in momentum = (mass × final velocity) - (mass × initial velocity)

Since the initial velocity is not given, we assume it to be zero. Thus, the equation becomes:

Impulse = (mass × final velocity) - (mass × 0) = mass × final velocity

Substituting the given values, we have:

Impulse = 1 kg × 2 m/s = 2 kg·m/s

Therefore, the impulse exerted on the body is 2 kg·m/s.
