Question

problem 2: solve for mass (m) an engine accelerates a large industrial block at a rate of 3 m/s^2. the engine applies 250 n of applied force, and the total friction acting on the block is 49 n. what is the net force (f net) acting on the block? what is the mass (m) of the block? final answer for m: ____________ kg

Explanation:

Step1: Calculate net force

The net force ($F_{net}$) is the applied force minus the frictional force. So $F_{net}=F_{applied}-F_{friction}$. Given $F_{applied} = 250\ N$ and $F_{friction}=49\ N$.
$F_{net}=250 - 49=201\ N$

Step2: Calculate mass

According to Newton's second - law $F = ma$, where $F = F_{net}$, $a = 3\ m/s^{2}$. We can solve for mass $m=\frac{F_{net}}{a}$.
$m=\frac{201}{3}=67\ kg$

Answer:

67
