Question

С какой скоростью должна лететь хоккейная шайба массой 160г чтобы её импульс был равен импульсу пули массой 0,8 г летящий со скоростью 600 м /с

Answer 1

Дано:
m1=160г
m2=8г

Найти:
v1-?

Решение
v=m2*v/m1=8г*600м/с/160г=30м/с

Answer 2

Ну воот,нормально? Пожалуйста

Answer 3

Calculating the Speed of the Hockey Puck

To calculate the speed at which the hockey puck should be flying, we can use the principle of conservation of momentum. The momentum of an object is equal to its mass multiplied by its velocity. In this case, we want the momentum of the hockey puck to be equal to the momentum of the bullet.

The momentum of an object can be calculated using the formula:

Momentum = mass × velocity

Let's denote the mass of the hockey puck as m1 (160g) and the mass of the bullet as m2 (0.8g). We also know the velocity of the bullet, which is 600 m/s.

To find the velocity of the hockey puck, we can set up the following equation:

m1 × v1 = m2 × v2

where v1 is the velocity of the hockey puck.

Substituting the given values, we have:

160g × v1 = 0.8g × 600 m/s

Now, let's solve for v1:

v1 = (0.8g × 600 m/s) / 160g

Calculating this expression, we find:

v1 ≈ 3 m/s

Therefore, the hockey puck should be flying at a speed of approximately 3 m/s to have the same momentum as the bullet.

Please note that this calculation assumes an ideal scenario without considering factors such as air resistance or friction.
