Question

a runner has a mass of 68 kg and an acceleration of 1.5 m/s². determine the runners net force applied to the ground. 75 n 102 n 453 n 105 n

Explanation:

Step1: Recall Newton's second - law formula

$F = ma$, where $F$ is the net force, $m$ is the mass, and $a$ is the acceleration.

Step2: Substitute given values

Given $m = 68\ kg$ and $a=1.5\ m/s^{2}$. Then $F=(68\ kg)\times(1.5\ m/s^{2})$.

Step3: Calculate the result

$F = 102\ N$.

Answer:

$102\ N$
