Question

you paddle a canoe with a force of 156 n. you and the canoe have a combined mass of 220 kg. what is the acceleration of the canoe?

a. 1.1 m/s²
b. 0.7 m/s²
c. 1.4 m/s²
d. 2.3 m/s²

Explanation:

Step1: Recall Newton's second law

$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. We need to solve for $a$.

Step2: Rearrange the formula for acceleration

$a=\frac{F}{m}$

Step3: Substitute given values

Given $F = 156\ N$ and $m=220\ kg$, so $a=\frac{156}{220}\ m/s^{2}\approx0.7\ m/s^{2}$

Answer:

B. $0.7\ m/s^{2}$
