A basketball has a mass of 1 kg and is traveling 15 m/s. How fast would a 5 kg bowling ball have to travel to have the same momentum?

Question 5 options:

1 m/s

3 m/s

5 m/s

15 m/s

1 answer

Momentum is calculated using the formula:

\[ \text{Momentum} = \text{mass} \times \text{velocity} \]

First, we find the momentum of the basketball:

\[ \text{Momentum}_{\text{basketball}} = 1, \text{kg} \times 15, \text{m/s} = 15, \text{kg m/s} \]

To find the velocity of the bowling ball that would give it the same momentum, we can set the momentum of the bowling ball equal to the momentum of the basketball:

\[ \text{Momentum}_{\text{bowling ball}} = \text{mass} \times \text{velocity} = 5, \text{kg} \times v \]

Setting the two momenta equal:

\[ 15, \text{kg m/s} = 5, \text{kg} \times v \]

Now, we solve for \(v\):

\[ v = \frac{15, \text{kg m/s}}{5, \text{kg}} = 3, \text{m/s} \]

Thus, the bowling ball would need to travel at 3 m/s to have the same momentum as the basketball.

So, the answer is:

3 m/s
