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? will accelerate less because equals less acceleration.

Explanation:

Step1: Recall Newton's second - law

According to Newton's second - law $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. Rearranging for acceleration gives $a=\frac{F}{m}$. Assuming the mass of the baseball is constant.

Step2: Compare the accelerations

Since $a=\frac{F}{m}$, when $m$ is constant, a smaller force results in a smaller acceleration. The first throw has a force $F_1 = 15N$ and the second throw has a force $F_2=20N$. Because $F_1

Answer:

The first throw; a smaller force
