Which has more momentum, a speeding baseball or an ocean liner at rest in a harbor?

A) Baseball.
B) Ocean liner.
C) Both the same.
D) Can't say without more information.

If v = 0, momentum is zero

Hey, answer some of these yourself.

To determine which object has more momentum, let's first understand what momentum is. Momentum is defined as the mass of an object multiplied by its velocity. In equation form, it can be represented as:

Momentum = mass * velocity

Now let's compare the two objects:
1) Speeding baseball: A baseball has a relatively small mass compared to an ocean liner, but it can travel at a high velocity when hit by a bat. So, the baseball has a non-negligible amount of momentum.

2) Ocean liner at rest in a harbor: An ocean liner, although it has an enormous mass, is not moving in this scenario. As velocity is a crucial factor, the ocean liner has zero velocity, resulting in zero momentum.

Comparing the momentum of the speeding baseball (non-zero momentum) and the ocean liner at rest (zero momentum), we can conclude that the baseball has more momentum than the ocean liner.

Therefore, the answer is A) Baseball.
