Brainliest if the answer is correct, but please help.

Assuming all objects are moving with the same velocity, which statement describes the object with the largest inertia?

A bowling ball rolls across a street and into a large soccer field.
A driver continues forward after his car takes a sharp turn.
A helicopter is following a high-speed pursuit across town.
A pebble is thrown in space and continues in a straight line.

I was almost certain it was the driver, but now I'm debating with the bowling ball.
