Question

1. a 68 kg runner exerts a force of 59 n. what is the acceleration of the runner? 38.25 m/s^2 0.87 m/s^2 4012 n 1.15 m/s^2

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 \(F = 59\space N\) and \(m=68\space kg\). Substitute into the formula: \(a=\frac{59}{68}\).

Step3: Calculate the value

\(\frac{59}{68}\approx0.87\space m/s^{2}\)

Answer:

\(0.87\space m/s^{2}\) (the second option)
