Answer to Question #142822 in Physics for roop

Question

A net force of 126N (S) is applied to a 70 Kg sprinter. Determine the acceleration of the sprinter

Answer 1

We can find the acceleration of the sprinter from the Newton's Second Law of Motion:

$$F_{net}=ma,$$ $$a=\dfrac{F_{net}}{m}=\dfrac{126\ N\ [S]}{70\ kg}=1.8\ \dfrac{m}{s^2}\ [S].$$

Answer:

$a=1.8\ \dfrac{m}{s^2}\ [S].$
