Question

Тележка массой 200г двигается равномерно по горизонтальной поверхности стола со скоростью 2м/с. Чему равен её импульс? .

Answer 1

P=mw  P=0.2кг*2м\с=0.4кг*м\с

Answer 2

Calculation of Impulse

To calculate the impulse of an object, we need to multiply its mass by its velocity. In this case, the mass of the cart is 200 grams, which is equivalent to 0.2 kilograms, and its velocity is 2 m/s. Therefore, the impulse can be calculated as follows:

Impulse = Mass × Velocity

Impulse = 0.2 kg × 2 m/s

Impulse = 0.4 kg·m/s

So, the impulse of the cart is 0.4 kg·m/s.
