Answer 2

Calculating the Total Momentum of the Two Balls

To calculate the total momentum of the two balls, we can use the formula:

Total Momentum = Momentum of Ball 1 + Momentum of Ball 2

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

Momentum = mass × velocity

Let's calculate the momentum of each ball and then find the total momentum.

Momentum of Ball 1:

The mass of Ball 1 is 200 g and its velocity is 4 m/s. Using the formula, Momentum = mass × velocity, we get: Momentum of Ball 1 = 200 g × 4 m/s

Momentum of Ball 2:

The mass of Ball 2 is 100 g and its velocity is 3 m/s. Using the formula, Momentum = mass × velocity, we get: Momentum of Ball 2 = 100 g × 3 m/s

Calculating the Total Momentum:

Now, let's calculate the total momentum by adding the momentum of Ball 1 and Ball 2: Total Momentum = Momentum of Ball 1 + Momentum of Ball 2

Result:

The total momentum of the two balls can be calculated using the above steps.
