Question

an object with a mass of 41.8 kg accelerates upward at 9.3 m/s². what amount of force acts on the object? (a) what are you solving for? a acceleration b mass c force (b) what is the equation you need to use to solve this problem? a m = f/a b a = f/m c f = m · a (c) what is your answer? a 32.5 b 4.49

Explanation:

Step1: Identify the formula

Newton's second - law formula is $F = m\times a$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Substitute the given values

Given $m = 41.8\ kg$ and $a=9.3\ m/s^{2}$. Substitute into $F = m\times a$.
$F=41.8\times9.3$

Step3: Calculate the force

$F = 41.8\times9.3=398.74\ N$

Answer:

398.74 N
