Question

what is the acceleration of a baseball if it has a mass of 0.145 kg and hits the catchers glove with a force of 25 n?
0.0058 m/s2
3.625 m/s2
172.4 m/s2
85 m/s2

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\), where \(F\) is force, \(m\) is mass, and \(a\) is acceleration. We need to solve for \(a\), so the formula becomes \(a=\frac{F}{m}\).

Step2: Substitute the given values

Given \(F = 25\space N\) and \(m=0.145\space kg\). Substitute into \(a=\frac{F}{m}\), we get \(a = \frac{25}{0.145}\).

Step3: Calculate the value of \(a\)

\(a=\frac{25}{0.145}\approx172.4\space m/s^{2}\)

Answer:

172.4 m/s2
