You can't determine the acceleration of the ball just from the force applied and its mass. Here's why:

* Force and Acceleration are Linked, but Not the Same: Newton's Second Law of Motion states: Force = Mass x Acceleration (F = ma)

* Unknown Factors: To calculate acceleration (a), we need to know both the force (F) and the mass (m). You've provided the mass (1 kg) and the force (25 N), but there's a missing piece.

Example:

Let's say you apply a 25 N force to the ball. To find the acceleration, we'd use:

* a = F / m

* a = 25 N / 1 kg

* a = 25 m/s²

Key Takeaway: The force you apply determines the acceleration, but you need to consider the mass of the object as well.
