False
Explanation
## Step 1### The formula for momentum is given by
, where
is the momentum,
is the mass, and
is the velocity. ## Step 2Using the above formula, we can calculate the momentum of the ball. The mass of the ball is 5 kg and its velocity is 30 m/s. Substituting these values into the formula, we get
.## Step 3Similarly, we can calculate the momentum of the box. The mass of the box is 20 kg and its velocity is 0.75 m/s. Substituting these values into the formula, we get
.## Step 4Comparing the momentum of the ball and the box, we can see that they are not the same. Therefore, the statement is false.
