I have no idea how to do this, and I'm not sure what the formula is. Here's my question: In space, there is almost no air, so there is virtually no friction. If an astronaut throws a ball in space with an initial velocity of 3.0 meters per second to the west, what will the ball's velocity be in a year? Assume there are no nearby planets.

the velocity remains the same?

To find out the ball's velocity in a year, we first need to determine the acceleration acting on the ball. In this case, we can neglect air resistance and assume that the only force acting on the ball is its initial velocity.

In the absence of any external forces, an object will continue to move with constant velocity. Therefore, the ball's velocity will remain constant over time unless another force acts on it.

Since there are no nearby planets to exert gravitational forces or any other forces acting on the ball, the initial velocity of the ball will remain unchanged throughout the year. Therefore, the ball's velocity after a year will still be 3.0 meters per second to the west.

The answer is FIGURE IT OUT YOURSELF!
