Question

a baseball player throws a baseball twice. the first throw he used 15 n of force and the 2nd throw he used 20 n. which throw will accelerate less?
dropdown will accelerate less because dropdown equals less acceleration.

Explanation:

Step1: Recall Newton's Second Law

Newton's second law states that \( F = ma \), where \( F \) is force, \( m \) is mass, and \( a \) is acceleration. Rearranging for acceleration, we get \( a=\frac{F}{m} \). For the same mass (the baseball's mass is constant), acceleration is directly proportional to the force applied.

Step2: Compare the Forces

The first throw has a force of \( 15\,\text{N} \) and the second has \( 20\,\text{N} \). Since \( a\propto F \) (for constant \( m \)), a smaller force will result in a smaller acceleration. So the throw with \( 15\,\text{N} \) (the first throw) will have less acceleration.

Answer:

The first throw (using 15 N) will accelerate less because less force equals less acceleration.
