newtons laws quiz
calculate the answer and write in the box below.
what force is necessary for a 75 kilogram runner to accelerate at 4.0 m/s²?

Explanation:

Step1: Identify the formula

Use Newton's second - law $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Substitute the values

Given $m = 75\ kg$ and $a=4.0\ m/s^{2}$, then $F=(75\ kg)\times(4.0\ m/s^{2})$.

Step3: Calculate the force

$F = 300\ N$.

Answer:

300
