Question

question 21 (problem reference 4 - 1) a 23.0 kg apple crate accelerates along a frictionless, horizontal surface as the crate is pulled with an applied force of 14.5 n as shown in the drawing. what is the weight of the crate? 225 n 140 n 23.0 n 9.80 n

Explanation:

Step1: Recall weight formula

The weight formula is $W = mg$, where $m$ is mass and $g$ is acceleration due to gravity ($g = 9.8\ m/s^{2}$).

Step2: Substitute values

Given $m = 23.0\ kg$ and $g=9.8\ m/s^{2}$, then $W=23.0\times9.8$.
$W = 225.4\ N\approx225\ N$.

Answer:

225 N
