Question

problem 2 you push a desk to move it, and it accelerates at 0.4 m/s². given the total horizontal force on the desk is 32 n, find the mass of the desk.

Explanation:

Step1: Identify the formula

According to Newton's second - law $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. We need to solve for $m$, so $m=\frac{F}{a}$.

Step2: Substitute the values

Given $F = 32N$ and $a=0.4m/s^{2}$. Substitute these values into the formula: $m=\frac{32}{0.4}$.

Step3: Calculate the mass

$m = 80kg$.

Answer:

$80kg$
